{{Windows Vista}}

'''Windows Vista''' is<!--Attention: Do NOT change to "was". This violates [[MOS:TENSE]], which specifies that all articles on operating systems are written in the present tense, even if discontinued.--> a major release of the [[Windows NT]] operating system developed by [[Microsoft]]. It was the direct successor to [[Windows XP]], released five years earlier, which was then the longest time span between successive releases of Microsoft Windows. It was [[Software release life cycle#Release to manufacturing (RTM)|released to manufacturing]] on November 8, 2006, and over the following two months, it was released in stages to business customers, [[original equipment manufacturers]] (OEMs), and retail channels. On January 30, 2007, it was released internationally and was made available for purchase and download from the [[Windows Marketplace]]; it is the first release of Windows to be made available through a [[digital distribution platform]].<ref name="WindowsVistaMarketplace">{{cite web |url=https://news.microsoft.com/2007/01/17/microsoft-unveils-new-ways-for-consumers-to-get-windows-vista/ |title=Microsoft Unveils New Ways for Consumers to Get Windows Vista |date=January 17, 2007 |publisher=[[Microsoft]] |work=News Center |access-date=September 9, 2022 |archive-date=January 3, 2017 |archive-url=https://web.archive.org/web/20170103174146/http://news.microsoft.com/2007/01/17/microsoft-unveils-new-ways-for-consumers-to-get-windows-vista/ |url-status=live }}</ref>

[[Development of Windows Vista]] began in 2001 under the codename "Longhorn"; originally envisioned as a minor successor to Windows XP, it [[feature creep|gradually included numerous new features]] from the then-next major release of Windows codenamed "Blackcomb", after which it was repositioned as a major release of Windows, and it subsequently [[development hell|underwent a period of protracted development]] that was unprecedented for Microsoft. Most new features were prominently based on a new presentation layer codenamed [[Windows Presentation Foundation|Avalon]], a new communications architecture codenamed [[Windows Communication Foundation|Indigo]], and a relational storage platform codenamed [[WinFS]] — all built on the [[.NET Framework]]; however, this proved to be untenable due to incompleteness of technologies and ways in which new features were added, and Microsoft reset the project in 2004. Many features were eventually reimplemented after the reset, but Microsoft ceased using [[managed code]] to develop the operating system.<ref name="DVDMakerFAQ">{{cite web |url=http://blogs.msdn.com/ericgu/archive/2006/01/09/windows-dvd-maker-faq.aspx |title=Windows DVD Maker FAQ |last=Gunnerson |first=Eric |date=January 9, 2006 |archive-url=https://web.archive.org/web/20070525111801/http://blogs.msdn.com/ericgu/archive/2006/01/09/windows-dvd-maker-faq.aspx |quote=I would have loved to use managed code for the UI part, which is what I own.

[[Features new to Windows Vista|New features of Windows Vista]] include a [[graphical user interface]] and [[Skin (computing)|visual style]] referred to as [[Windows Aero]]; a [[content index]] and [[desktop search]] platform called [[Windows Search]]; new [[peer-to-peer]] technologies to simplify sharing [[computer file|files]] and [[digital media|media]] between computers and devices on a [[home network]]; and new multimedia tools such as [[Windows DVD Maker]]. Windows Vista included version 3.0 of the [[.NET Framework]], allowing [[software developer]]s to write applications without traditional [[Windows API]]s. There are major architectural overhauls to audio, display, network, and print sub-systems; deployment, installation, servicing, and startup procedures are also revised. It is the first release of Windows built on Microsoft's [[Trustworthy Computing]] initiative and emphasized security with the introduction of many new [[Security and safety features new to Windows Vista|security and safety features]] such as [[BitLocker]] and [[User Account Control]].

The ambitiousness and scope of these changes, and the abundance of new features earned positive reviews, but Windows Vista was the subject of frequent negative press and significant criticism. [[Criticism of Windows Vista]] focused on driver, peripheral, and program incompatibility; [[digital rights management]]; excessive authorization from the new User Account Control; inordinately high [[system requirements]] when contrasted with Windows XP; its protracted development; longer [[boot time]]; and more restrictive product licensing. Windows Vista deployment and satisfaction rates were consequently lower than those of Windows XP, and it is considered a market failure;<ref name="FiveReasonsFailed">{{cite web |url=https://www.zdnet.com/article/the-top-five-reasons-why-windows-vista-failed/ |title=The top five reasons why Windows Vista failed |last=Hiner |first=Jason |date=October 5, 2008 |publisher=[[Red Ventures]] |work=[[ZDNet]] |access-date=August 25, 2023 |archive-date=February 23, 2024 |archive-url=https://web.archive.org/web/20240223042929/https://www.zdnet.com/article/the-top-five-reasons-why-windows-vista-failed/ |url-status=live }}</ref><ref name="TechTalkers">{{cite web |url=https://medium.com/techtalkers/windows-vista-why-did-it-fail-b3ba4bd08a74 |title=Windows Vista: Why did it fail? |work=Medium |first=Nithil |last=Krishnaraj |date=June 22, 2020 |access-date=June 16, 2023 |archive-date=January 7, 2024 |archive-url=https://web.archive.org/web/20240107004710/https://medium.com/techtalkers/windows-vista-why-did-it-fail-b3ba4bd08a74 |url-status=live }}</ref> however, its use surpassed Microsoft's pre-launch two-year-out expectations of achieving 200 million users<ref name="RalliesDevelopers">{{cite web |url=https://www.zdnet.com/article/microsoft-rallies-developers-behind-vista/ |title=Microsoft rallies developers behind Vista |last=Broersma |first=Matthew |date=September 19, 2006 |publisher=[[Red Ventures]] |work=[[ZDNet]] |access-date=September 9, 2022 |archive-date=July 1, 2022 |archive-url=https://web.archive.org/web/20220701154136/https://www.zdnet.com/article/microsoft-rallies-developers-behind-vista/ |url-status=live }}</ref> (with an estimated 330 million users by 2009).<ref name="LicensesSoldArs">{{cite web |url=https://arstechnica.com/information-technology/2011/04/windows-7-350-million-licenses-sold-in-18-months/ |title=Windows 7: 350 million licenses sold in 18 months |date=April 22, 2011 |publisher=[[Condé Nast]] |work=[[Ars Technica]] |access-date=August 25, 2023 |archive-date=March 13, 2023 |archive-url=https://web.archive.org/web/20230313090719/https://arstechnica.com/information-technology/2011/04/windows-7-350-million-licenses-sold-in-18-months/ |url-status=live }}</ref> Two [[service pack]]s were released, in 2008 and 2009 respectively.

Microsoft began work on Windows Vista, known at the time by its [[codename]] "Longhorn", in May 2001,<ref>{{cite magazine

}}</ref> five months before the release of [[Windows XP]]. It was originally expected to ship in October 2003 as a minor step between Windows XP and "Blackcomb", which was planned to be the company's next major operating system release. Gradually, "Longhorn" assimilated many of the important new features and technologies slated for Blackcomb, resulting in the release date being pushed back several times in three years. In some builds of Longhorn, their license agreement said "For the Microsoft product codenamed 'Whistler'". Many of Microsoft's developers were also re-tasked to build updates to Windows XP and [[Windows Server 2003]] to strengthen security. Faced with ongoing delays and concerns about [[feature creep]], Microsoft announced on August 27, 2004, that it had revised its plans. For this reason, Longhorn was reset to start work on componentizing the Windows Server 2003 Service Pack 1 codebase, and over time re-incorporating the features that would be intended for an actual operating system release. However, some previously announced features such as [[WinFS]] were dropped or postponed, and a new software development methodology called the [[Security Development Lifecycle]] was incorporated to address concerns with the security of the Windows codebase, which is programmed in [[C (programming language)|C]], [[C++]] and [[Assembly language|assembly]]. Longhorn became known as Vista in 2005. ''Vista'' in Spanish means view.<ref>[https://www.microsoft.com/technet/archive/winntas/training/ntarchitectoview/ntarc_2.mspx Microsoft Windows System Overview]. Microsoft.com.

=== Longhorn ===
[[File:Microsoft Codename LongHorn v6.0 Build 4074.png|thumb|Desktop screenshot of Windows Longhorn build 4074, showing the [[Start menu]], an early version of [[Windows Desktop Gadgets|Windows Desktop Sidebar]], Windows Explorer, and the Slate visual style]]
The early development stages of Longhorn were generally characterized by incremental improvements and updates to Windows XP. During this period, Microsoft was fairly quiet about what was being worked on, as their marketing and public relations efforts were more strongly focused on Windows XP, and [[Windows Server 2003]], which was released in April 2003. Occasional builds of Longhorn were leaked onto popular [[Legal aspects of file sharing|file sharing]] networks such as [[IRC]], [[BitTorrent]], [[eDonkey network|eDonkey]] and various [[newsgroup]]s, and so most of what is known about builds before the first sanctioned development release of Longhorn in May 2003 is derived from these builds.

After several months of relatively little news or activity from Microsoft with Longhorn, Microsoft released Build 4008, which had made an appearance on the Internet around February 28, 2003.<ref name="build4008">{{cite web

}}</ref> It was also privately handed out to a select group of software developers. As an evolutionary release over build 3683, it contained several small improvements, including a modified blue "Plex" theme and a new, simplified Windows Image-based installer that operates in graphical mode from the outset, and completed an install of the operating system in approximately one third the time of Windows XP on the same hardware. An optional "new taskbar" was introduced that was thinner than the previous build and displayed the time differently.
The most notable visual and functional difference, however, came with Windows Explorer. The incorporation of the Plex theme made blue the dominant color of the entire application. The Windows XP-style task pane was almost completely replaced with a large horizontal pane that appeared under the toolbars. A new search interface allowed for filtering of results, searching for Windows help, and natural-language queries that would be used to integrate with WinFS. The animated search characters were also removed. The "view modes" were also replaced with a single slider that would resize the icons in real-time, in the list, thumbnail, or details mode, depending on where the slider was. File metadata was also made more visible and more easily editable, with more active encouragement to fill out missing pieces of information. Also of note was the conversion of Windows Explorer to being a [[.NET Framework|.NET]] application.

Most builds of Longhorn and Vista were identified by a label that was always displayed in the bottom-right corner of the desktop. A typical build label would look like "Longhorn Build 3683.Lab06_N.020923-1821". Higher build numbers did not automatically mean that the latest features from every development team at Microsoft was included. Typically, a team working on a certain feature or subsystem would generate their working builds which developers would test with, and when the code was deemed stable, all the changes would be incorporated back into the main development tree at once. At Microsoft, several "Build labs" exist where the compilation of the entirety of Windows can be performed by a team. The name of the lab in which any given build originated is shown as part of the build label, and the date and time of the build follow that. Some builds (such as Beta 1 and Beta 2) only display the build label in the version information dialog (Winver). The icons used in these builds are from Windows XP.

At the [[Windows Hardware Engineering Conference]] (WinHEC) in May 2003, Microsoft gave their first public demonstrations of the new Desktop Window Manager and [[Windows Aero|Aero]]. The demonstrations were done on a revised build 4015 which was never released. Several sessions for developers and hardware engineers at the conference focused on these new features, as well as the [[Next-Generation Secure Computing Base]] (previously known as "Palladium"), which at the time was Microsoft's proposed solution for creating a secure computing environment whereby any given component of the system could be deemed "trusted". Also at this conference, Microsoft reiterated their roadmap for delivering Longhorn, pointing to an "early 2005" release date.<ref name="winhec2003">{{cite web

=== Development reset ===
By 2004, it had become obvious to the Windows team at Microsoft that they were losing sight of what needed to be done to complete the next version of Windows and ship it to customers. Internally, some Microsoft employees were describing the Longhorn project as "another Cairo" or "Cairo.NET", referring to the [[Cairo (operating system)|Cairo development project]] that the company embarked on through the first half of the 1990s, which never resulted in a shipping operating system (though nearly all the technologies developed in that time did end up in [[Windows 95]] and [[Windows NT]]<ref name="caplancairo">{{cite web

}}</ref>). Microsoft was shocked in 2005 by Apple's release of [[Mac OS X Tiger]]. It offered only a limited subset of features planned for Longhorn, in particular fast file searching and integrated graphics and sound processing, but appeared to have impressive reliability and performance compared to contemporary Longhorn builds.<ref>{{cite web|url=http://www.informationweek.co.uk/microsofts-vista-had-major-mac-envy-comp/197001418|title=Microsoft's Vista Had Major Mac Envy, Company E-Mails Reveal|first=Gregg |last=Keizer| work=[[InformationWeek]]|publisher=[[UBM plc]]|date=January 29, 2007|access-date=February 28, 2013|archive-url=https://web.archive.org/web/20140127195804/http://www.informationweek.com/microsofts-vista-had-major-mac-envy-company-e-mails-reveal/d/d-id/1051287 |archive-date=January 27, 2014}}</ref> Most Longhorn builds had major [[Windows Explorer]] system leaks which prevented the OS from performing well, and added more confusion to the development teams in later builds with more and more code being developed which failed to reach stability.

Allchin went on to explain how in December 2003, he enlisted the help of two other senior executives, Brian Valentine and Amitabh Srivastava, the former being experienced with shipping software at Microsoft, most notably Windows Server 2003,<ref name="supersitevalentine">{{cite web

}}</ref>) that would componentize existing Windows Server 2003 source code, and over time add back functionality as development progressed. Future Longhorn builds would start from Windows Server 2003 Service Pack 1 and continue from there.

This change, announced internally to Microsoft employees on August 26, 2004, began in earnest in September, though it would take several more months before the new development process and build methodology would be used by all of the development teams. A number of complaints came from individual developers, and Bill Gates himself, that the new development process was going to be prohibitively difficult to work within.

=== As Windows Vista ===
By approximately November 2004, the company had considered several names for the final release, ranging from simple to fanciful and inventive. In the end, Microsoft chose Windows Vista as confirmed on July 22, 2005, believing it to be a "wonderful intersection of what the product really does, what Windows stands for, and what resonates with customers, and their needs". Group Project Manager Greg Sullivan told Paul Thurrott "You want the PC to adapt to you and help you cut through the clutter to focus on what's important to you. That's what Windows Vista is all about: "bringing clarity to your world" (a reference to the three marketing points of Vista—Clear, Connected, Confident), so you can focus on what matters to you".<ref>{{cite web|url=https://www.cnet.com/news/longhorns-new-name-windows-vista/|title=Longhorn's new name: Windows Vista|first=Mike|last=Ricciuti|work=[[CNET]]|publisher=[[CBS Interactive]]|date=July 22, 2005|access-date=March 15, 2016|archive-date=March 9, 2016|archive-url=https://web.archive.org/web/20160309184708/http://www.cnet.com/news/longhorns-new-name-windows-vista/|url-status=live}}</ref> Microsoft co-president Jim Allchin also loved the name, saying that "Vista creates the right imagery for the new product capabilities and inspires the imagination with all the possibilities of what can be done with Windows—making people's passions come alive."<ref name="roadtogold4">{{cite web

After Longhorn was named Windows Vista in July 2005, an unprecedented [[Development stage|beta-test]] program was started, involving hundreds of thousands of volunteers and companies. In September of that year, Microsoft started releasing regular [[Community Technology Preview]]s (CTP) to beta testers from July 2005 to February 2006. The first of these was distributed at the 2005 Microsoft [[Professional Developers Conference]], and was subsequently released to beta testers and [[Microsoft Developer Network]] subscribers. The builds that followed incorporated most of the planned features for the final product, as well as a number of changes to the user interface, based largely on feedback from beta testers. Windows Vista was deemed feature-complete with the release of the "February CTP", released on February 22, 2006, and much of the remainder of the work between that build and the final release of the product focused on stability, performance, application and driver compatibility, and documentation. Beta 2, released in late May, was the first build to be made available to the general public through Microsoft's Customer Preview Program. It was downloaded over 5 million times. Two release candidates followed in September and October, both of which were made available to a large number of users.<ref>{{cite web | first=Paul | last=Thurrott  | url=http://www.winsupersite.com/showcase/winvista_roadtogold_07.asp | title=Paul Thurrott's SuperSite for Windows: Road to Gold: The Long Road to Windows Vista Part 7: July 2006 – present | work=SuperSite for Windows |publisher=[[Penton (company)|Penton]] | date=November 5, 2006 | access-date=December 25, 2007 |archive-url=https://web.archive.org/web/20061109161522/http://www.winsupersite.com/showcase/winvista_roadtogold_07.asp |archive-date=November 9, 2006}}</ref>

At the [[Intel Developer Forum]] on March 9, 2006, Microsoft announced a change in their plans to support EFI in Windows Vista. The [[UEFI]] 2.0 specification (which replaced EFI 1.10) was not completed until early 2006, and at the time of Microsoft's announcement, no firmware manufacturers had completed a production implementation which could be used for testing. As a result, the decision was made to postpone the introduction of UEFI support to Windows; support for UEFI on 64-bit platforms was postponed until Vista Service Pack 1 and [[Windows Server 2008]] and 32-bit UEFI would not be supported, as Microsoft did not expect many such systems to be built because the market was quickly moving to 64-bit processors.<ref name="uefiremoved">{{cite web

While Microsoft had originally hoped to have the consumer versions of the operating system available worldwide in time for the 2006 [[holiday shopping season]], it announced in March 2006 that the release date would be pushed back to January 2007 in order to give the company—and the hardware and software companies that Microsoft depends on for providing [[device driver]]s—additional time to prepare. Because a [[release to manufacturing]] (RTM) build is the final version of code shipped to retailers and other distributors, the purpose of a pre-RTM build is to eliminate any last "show-stopper" bugs that may prevent the code from responsibly being shipped to customers, as well as anything else that consumers may find troublesome. Thus, it is unlikely that any major new features would be introduced; instead, work would focus on Vista's fit and finish. In just a few days, developers had managed to drop Vista's bug count from over 2470 on September 22 to just over 1400 by the time RC2 shipped in early October. However, they still had a way to go before Vista was ready to RTM. Microsoft's internal processes required Vista's bug count to drop to 500 or fewer before the product could go into escrow for RTM.<ref>{{cite web

On June 14, 2006, Windows developer Philip Su posted a blog entry which decried the development process of Windows Vista, stating that "The code is way too complicated, and that the pace of coding has been tremendously slowed down by overbearing process."<ref>{{cite web

Windows Vista build 5824 (October 17, 2006) was supposed to be the RTM release, but a bug, where the OOBE hangs at the start of the WinSAT Assessment (if upgraded from Windows XP), requiring the user to terminate msoobe.exe by pressing Shift+F10 to open Command Prompt using either command-line tools or Task Manager prevented this, damaging development and lowering the chance that it would hit its January 2007 deadline.<ref name="Windows Vista RTM code delayed">{{cite web | url=http://www.alphr.com/news/business-software/96607/vista-rtm-code-delayed-report | title=Windows Vista RTM code delayed | first=Steve | last=Malone | publisher=Digitimes/alphr | date=October 27, 2006 | access-date=August 20, 2015 | archive-date=January 12, 2016 | archive-url=https://web.archive.org/web/20160112051232/http://www.alphr.com/news/business-software/96607/vista-rtm-code-delayed-report | url-status=live }}</ref>

{{Main| Features new to Windows Vista}}
New features introduced by Windows Vista are very numerous, encompassing significant functionality not available in its predecessors.
=== End-user ===
* '''[[Windows Aero]]''' is the new graphical user interface, which Jim Allchin stated is an acronym for ''Authentic, Energetic, Reflective, and Open''.<ref name="WindowsVistaSounds">{{cite web |url=http://windowsvistablog.com/blogs/windowsvista/archive/2006/11/09/the-sounds-of-windows-vista.aspx |title=The Sounds of Windows Vista |last=Allchin |first=Jim |author-link=Jim Allchin |date=November 9, 2006 |archive-url=https://web.archive.org/web/20061110152317/http://windowsvistablog.com/blogs/windowsvista/archive/2006/11/09/the-sounds-of-windows-vista.aspx |archive-date=November 10, 2006 |publisher=[[Microsoft]] |work=Windows Vista Team Blog |access-date=April 25, 2015}}</ref> Microsoft intended the new interface to be cleaner and more aesthetically pleasing than those of previous Windows versions, and it features advanced visual effects such as blurred glass translucencies and dynamic glass reflections and smooth window animations.<ref name="WVPG"/> Laptop users report, however, that enabling Aero reduces battery life<ref>{{cite web |url=https://www.engadget.com/2007/05/04/vistas-aero-interface-blamed-for-truncated-battery-life/ |title=Vista's Aero interface blamed for truncated battery life |first=Darren |last=Murph |publisher=[[Engadget]] |date=May 3, 2007 |access-date=September 18, 2017 |archive-date=June 27, 2017 |archive-url=https://web.archive.org/web/20170627053108/https://www.engadget.com/2007/05/04/vistas-aero-interface-blamed-for-truncated-battery-life/ |url-status=live }}</ref><ref>{{cite web |url=http://blogs.msdn.com/coding4fun/archive/2007/05/06/2452864.aspx |title=Vista Battery Fix? |date=May 6, 2007 |publisher=[[Microsoft]] |access-date=March 18, 2008 |archive-url=https://web.archive.org/web/20080313152247/http://blogs.msdn.com/coding4fun/archive/2007/05/06/2452864.aspx |archive-date=March 13, 2008 |url-status=dead }}</ref> and reduces performance. Windows Aero requires a [[compositing window manager]] called [[Desktop Window Manager]].
* '''[[Windows Shell]]''' offers a new range of organization, navigation, and search capabilities: Task Panes in [[Windows Explorer]] are removed, with the relevant tasks moved to a new command bar. The navigation pane can now be displayed when tasks are available, and it has been updated to include a new "Favorite Links" that houses shortcuts to common locations. An [[incremental search]] search box now appears at all times in Windows Explorer. The address bar has been replaced with a [[breadcrumb navigation]] bar, which means that multiple locations in a hierarchy can be navigated without needing to go back and forth between locations. Icons now display thumbnails depicting contents of items and can be dynamically scaled in size (up to 256 × 256 pixels). A new preview pane allows users to see thumbnails of items and play tracks, read contents of documents, and view photos when they are selected. Groups of items are now selectable and display the number of items in each group. A new details pane allows users to manage [[metadata]]. There are several new sharing features, including the ability to directly share files. The [[Start menu]] also now includes an incremental search box — allowing the user to press the {{keypress|Win}} key and start typing to instantly find an item or launch a program — and the ''All Programs'' list uses a vertical scroll bar instead of the cascading flyout menu of Windows XP.<ref name="WVPG"/>
* '''[[Windows Search]]''' is a new content index desktop search platform that replaces the [[Indexing Service]] of previous Windows versions to enable incremental searches for files and non-file items — documents, emails, folders, programs, photos, tracks, and videos — and contents or details such as [[file attribute|attribute]]s, [[filename extension|extension]]s, and [[filename]]s across compatible applications.<ref name="WVPG"/>
* '''[[Windows Sidebar]]''' is a translucent panel that hosts gadgets that display details such as feeds and sports scores on the Windows desktop; the Sidebar can be hidden and gadgets can also be placed on the desktop itself.<ref name="WVPG"/>
* '''[[Internet Explorer 7]]''' is a significant revision over [[Internet Explorer 6]] with a new user interface comprising additional address bar features, a new search box, enhanced page zoom, [[RSS feed]] functionality, and support for [[tabbed browsing]] (with an optional "quick tabs" feature that shows thumbnails of each open tab). [[Anti-phishing software]] is introduced that combines client-side scanning with an optional online service; it checks with Microsoft the address being visited to determine its legitimacy, compares the address with a locally stored list of legitimate addresses, and uses heuristics to determine whether an address's characteristics are indicative of phishing attempts. In Windows Vista, it [[Mandatory Integrity Control|runs in isolation from other applications]] (protected mode); exploits and malicious software are restricted from writing to any location beyond Temporary Internet Files without explicit user consent.
* '''[[Windows Media Player 11]]''' is a significant update to Microsoft's [[Windows Media Player]] for playing and organizing photos, tracks, and videos. New features include an updated GUI for the media library, disc spanning, enhanced audio fingerprinting, instant search capabilities, item organization features, synchronization features, the ability to share the media library over a network with other Windows Vista machines, [[Xbox 360]] integration, and [[Windows Media Center Extender]] support.
* '''[[Windows Defender]]''' is an antispyware program with [[Windows Defender#Windows Vista-specific functionality|several configurable options]] for real-time protection, with settings to block and notify of changes to browser, security, and Windows settings; prohibit startup applications; and view network-connected applications and their addresses; users can optionally report detected threats through the [[Microsoft Active Protection Service]] to help stop new threats.
* '''[[Backup and Restore Center]]''' allows for the creation of periodic backups and backup schedules, as well as recovery from previous backups; backups are incremental, storing only subsequent changes, which minimizes disk space usage. Windows Vista Business, Windows Vista Enterprise, and Windows Vista Ultimate additionally include '''Windows Complete PC Backup''' that allows [[system image]]s to be created, and this feature can be started from Windows Vista installation media so that images can be restored to a new hard disk or new hardware or if a PC has experienced hardware failures and it cannot boot.
* '''[[Windows Calendar]]''' is a basic [[calendar application]] that integrates with Windows Contacts and Windows Mail; users can create appointments and tasks, publish calendars to the Internet or to a network share, receive reminders, send and receive calendar invitations, and share calendars with family members.
* '''[[Windows Mail]]''' is the successor to [[Outlook Express]] that includes significant feature additions (many of which were previously exclusive to [[Microsoft Outlook]]) and introduces fundamental revisions to the identification process, storage architecture, and security structure.<ref name="Datamation">{{cite web |url=http://www.datamation.com/entdev/article.php/3671106/Vista-Mail-vs-Outlook-Express.htm |title=Vista Mail vs. Outlook Express |last=Piltzecker |first=Tony |date=April 11, 2007 |work=[[Datamation]] |access-date=September 9, 2022 |archive-date=August 14, 2016 |archive-url=https://web.archive.org/web/20160814152411/http://www.datamation.com/entdev/article.php/3671106/Vista-Mail-vs-Outlook-Express.htm |url-status=live }}</ref>
* '''[[Windows Photo Gallery]]''' replaces Windows Picture and Fax Viewer; it can acquire photographs from digital cameras; adjust photograph effects; burn photographs to optical media; create [[Direct3D]]-accelerated slideshows; and reduce [[red-eye effect|red eye]].
* '''[[Windows Media Center]]''' previously exclusive to [[Windows XP Media Center Edition]] is available in Windows Vista Home Premium and Windows Vista Ultimate; it has been updated with many new features such as support for [[CableCARD]], DVD/MPEG-2, HD content, and two dual-tuner cards.
* '''[[Security and safety features new to Windows Vista#Parental Controls|Parental controls]]''' allow administrators to control and manage user activity (such as limiting the games that can be played or prohibiting specific contents of websites) of each standard user.<ref name="WVPG"/>
* '''Games''' including [[Microsoft FreeCell|FreeCell]], [[Hearts (Windows)|Hearts]], [[Microsoft Minesweeper|Minesweeper]], [[Solitaire (Windows)|Solitaire]], and [[Spider Solitaire (Windows)|Spider Solitaire]] have been rewritten in DirectX to take advantage of Windows Vista's new graphical capabilities.<ref name="UnderTheHood">{{cite web |url=http://blogs.msdn.com/b/greg_schechter/archive/2006/04/02/566767.aspx |title=The role of the Windows Display Driver Model in the DWM |last=Schechter |first=Greg |date=April 2, 2006 |publisher=[[Microsoft]] |website=[[MSDN]] |quote=The DWM operates in an environment where other DirectX applications do operate.

* '''[[Games Explorer]]''' is the central location for installed games that displays details such as covers, developers, genres, installation dates, play times, publishers, ratings, and versions. Customizable tasks for games are available; metadata for installed games can be updated from the Internet. Game-related settings such as audio options, community support options, game controller options, firewall settings, and parental controls are displayed.
* '''[[Windows Mobility Center]]''' centralizes settings and statuses relevant to mobile computing such as battery life, connectivity status, display brightness, screen orientation, synchronization status, and volume level, and new options can be added by OEMs.
* '''[[Windows Fax and Scan]]''' allows machines to create, receive, scan, and send faxes, with the goal of making fax management identical to working with email; it is available in Windows Vista Business, Windows Vista Enterprise, and Windows Vista Ultimate.
* '''[[Windows Meeting Space]]''' replaces [[NetMeeting]] and relies on [[Windows Vista networking technologies#People Near Me|People Near Me]] and [[WS-Discovery]] to identify participants on the local subnet or across the Internet; users can give control of their computers to other participants, project their desktops, send messages to participants, and share files.

* '''[[Shadow Copy]]''' (originally only available in Windows Server 2003) creates copies of files and folders on a scheduled basis, allowing users to recover multiple versions of deleted or overwritten files or folders. Incremental changes are saved by shadow copies, which helps to limit the disk space in use.
* '''[[Windows Update]]''' is now a native client application; in previous versions of Windows, it was a [[web application]] that had to be accessed from a web browser. Automatic Updates can now automatically download and install ''Recommended'' updates (in addition to ''High Priority'' updates that could be automatically downloaded and installed in previous versions of Windows). The prompt that appears when an update is installed that requires a machine to be [[reboot|restarted]] has been revised, with new options to postpone an operating system restart indefinitely, by 10 minutes, by 1 hour, or by 4 hours (in Windows XP, users could only repeatedly dismiss the prompt to restart, or allow the machine to be restarted within 15 minutes of its appearance).

The new driver model facilitates the new [[Desktop Window Manager]], which provides the [[screen tearing|tearing]]-free desktop and special effects that are the cornerstones of Windows Aero. Direct3D 10, developed in conjunction with major graphics card manufacturers, is a new architecture with more advanced [[shader]] support, and allows the [[graphics processing unit]] to render more complex scenes without assistance from the CPU. It features improved load balancing between CPU and GPU and also optimizes data transfer between them.<ref>{{cite web |url=http://blogs.technet.com/windowsvista/articles/447226.aspx |title=DirectX10: The Next Generation in Gaming |access-date=January 25, 2007 |work=Windows Vista Team Blog |date=August 16, 2006 |first=Nick |last=White |archive-date=November 18, 2008 |archive-url=https://web.archive.org/web/20081118053744/http://blogs.technet.com/windowsvista/articles/447226.aspx  }}</ref> WDDM also provides video content playback that rivals typical consumer electronics devices.

At the core of the [[operating system]], many improvements have been made to the memory manager, process scheduler and I/O scheduler.

[[User Account Control]], or UAC is perhaps the most significant and visible of these changes. UAC is a security technology that makes it possible for users to use their computer with fewer privileges by default, to stop [[malware]] from making unauthorized changes to the system. This was often difficult in previous versions of Windows, as the previous "limited" user accounts proved too restrictive and incompatible with a large proportion of application software, and even prevented some basic operations such as looking at the calendar from the notification tray. In Windows Vista, when an action is performed that requires administrative rights (such as installing/uninstalling software or making system-wide configuration changes), the user is first prompted for an administrator name and password; in cases where the user is already an administrator, the user is still prompted to confirm the pending privileged action. Regular use of the computer such as running programs, printing, or surfing the Internet does not trigger UAC prompts. User Account Control asks for credentials in a Secure Desktop mode, in which the entire screen is dimmed, and only the authorization window is active and highlighted. The intent is to stop a malicious program from misleading the user by interfering with the authorization window, and to hint to the user about the importance of the prompt.<ref>{{cite web|url=http://windowsdevcenter.com/pub/a/windows/2007/02/06/understanding-windows-vistas-user-account-control.html|title=Understanding Windows Vista's User Account Control|first1=William|last1=Stanek|first2=Paul|last2=Marquardt|date=February 6, 2007|work=windowsdevcenter.com|access-date=December 1, 2012|archive-date=October 16, 2012|archive-url=https://web.archive.org/web/20121016021306/http://windowsdevcenter.com/pub/a/windows/2007/02/06/understanding-windows-vistas-user-account-control.html|url-status=live}}</ref>

Testing by [[Symantec Corporation]] has proven the effectiveness of UAC. Symantec used over 2,000 active malware samples, consisting of [[backdoor (computing)|backdoors]], [[keyloggers]], [[rootkit]]s, mass mailers, [[Trojan horse (computing)|trojan horses]], [[spyware]], [[adware]], and various other samples. Each was executed on a default Windows Vista installation within a standard user account. UAC effectively blocked over 50 percent of each [[threat (computer)|threat]], excluding rootkits. 5 percent or less of the [[malware]] that evaded UAC survived a reboot.<ref>{{Cite web|date=2010-10-09|title=Malware Removal Guide|url=http://us.norton.com/support/premium_services/malware_removal_guide.pdf|access-date=2021-03-26|archive-url=https://web.archive.org/web/20101009013552/http://us.norton.com/support/premium_services/malware_removal_guide.pdf|archive-date=October 9, 2010}}</ref><ref>{{cite book |last1=NortonLive Team |title=Malware Removal Guide |date=February 2010 |publisher=Symantec |page=41}}</ref>

[[Internet Explorer|Internet Explorer 7]]'s new security and safety features include a [[phishing]] filter, [[Internationalized domain name|IDN]] with anti-spoofing capabilities, and integration with system-wide parental controls. For added security, [[ActiveX]] controls are disabled by default. Also, Internet Explorer operates in a protected mode, which operates with lower permissions than the user and runs in isolation from other applications in the operating system, preventing it from accessing or modifying anything besides the Temporary Internet Files directory.<ref name="protectedmodeie">Protected Mode IE has been described in detail at the Internet Explorer team blog: [http://blogs.msdn.com/ie/archive/2006/02/09/528963.aspx Protected Mode in Vista IE7] {{Webarchive|url=https://web.archive.org/web/20100123103719/http://blogs.msdn.com/ie/archive/2006/02/09/528963.aspx |date=January 23, 2010 }} and More details on Protected Mode IE in Windows Vista: http://blogs.msdn.com/ie/archive/2005/09/20/471975.aspx  {{Webarchive|url=https://web.archive.org/web/20060127003150/http://blogs.msdn.com/ie/archive/2005/09/20/471975.aspx |date=January 27, 2006 }}.</ref> Microsoft's anti-spyware product, ''[[Windows Defender]]'', has been incorporated into Windows, protecting against malware and other threats. Changes to various system configuration settings (such as new auto-starting applications) are blocked unless the user gives consent.

Whereas prior releases of Windows supported per-file encryption using [[Encrypting File System]], the Enterprise and Ultimate editions of Vista include [[BitLocker Drive Encryption]], which can protect entire [[volume (computing)|volumes]], notably the operating system volume. However, BitLocker requires approximately a 1.5-gigabyte partition to be permanently not encrypted and to contain system files for Windows to boot. In normal circumstances, the only time this partition is accessed is when the computer is booting, or when there is a Windows update that changes files in this area, which is a legitimate reason to access this section of the drive. The area can be a potential security issue, because a hexadecimal editor (such as dskprobe.exe), or malicious software running with administrator and/or kernel level privileges would be able to write to this "Ghost Partition" and allow a piece of malicious software to compromise the system, or disable the encryption. BitLocker can work in conjunction with a [[Trusted Platform Module]] (TPM) [[cryptoprocessor]] (version 1.2) embedded in a computer's [[motherboard]], or with a USB key.<ref name="exec-overview">{{cite web

A variety of other privilege-restriction techniques are also built into Vista. An example is the concept of "integrity levels" in user processes, whereby a process with a lower integrity level cannot interact with processes of a higher integrity level and cannot perform DLL–injection to processes of a higher integrity level. The security restrictions of [[Windows service]]s are more fine-grained, so that services (especially those listening on the network) cannot interact with parts of the operating system they do not need to. [[Obfuscation]] techniques such as [[address space layout randomization]] are used to increase the amount of effort required of [[malware]] before successful infiltration of a system. [[Code integrity]] verifies that system binaries have not been tampered with by malicious code.

As part of the redesign of the network stack, [[Windows Firewall]] has been upgraded, with new support for filtering both incoming and outgoing traffic. Advanced packet filter rules can be created that can grant or deny communications to specific services.

While much of the focus of Vista's new capabilities highlighted the new user interface,<ref>{{cite web|url=http://windows.microsoft.com/en-us/windows-vista/What-is-Windows-Aero|title=What is Windows Aero?|publisher=Microsoft|work=windows.microsoft.com|access-date=August 13, 2012|archive-date=January 29, 2013|archive-url=https://archive.today/20130129023057/http://windows.microsoft.com/en-US/windows-vista/What-is-Windows-Aero|url-status=live}}</ref> security technologies, and improvements to the core operating system, Microsoft also adding new deployment and maintenance features:

* The [[Windows Imaging Format]] (WIM) provides the cornerstone of Microsoft's new deployment and packaging system. WIM files, which contain a [[Hardware Abstraction Layer|HAL]]-independent image of Windows Vista, can be maintained and patched without having to rebuild new images. Windows Images can be delivered via [[Systems Management Server]] or Business Desktop Deployment technologies. Images can be customized and configured with applications then deployed to corporate client personal computers using little to no touch by a system administrator. [[ImageX]] is the Microsoft tool used to create and customize images.
* [[Windows Deployment Services]] replaces [[Remote Installation Services]] for deploying Vista and prior versions of Windows.
* Approximately 700 new [[Group Policy]] settings have been added, covering most aspects of the new features in the operating system, as well as significantly expanding the configurability of wireless networks, removable storage devices, and user desktop experience. Vista also introduced an XML-based format (ADMX) to display registry-based policy settings, making it easier to manage networks that span geographic locations and different languages.<ref name="gp">{{cite web

* [[Services for UNIX]], renamed as "Subsystem for UNIX-based Applications", comes with the Enterprise and Ultimate editions of Vista. [[Network File System]] (NFS) client support is also included.
* [[Multilingual User Interface]]–Unlike previous versions of Windows (which required the loading of language packs to provide local-language support), Windows Vista Ultimate and Enterprise editions support the ability to dynamically change languages based on the logged-on user's preference.
* Wireless Projector support

=== Developer ===
Windows Vista includes a large number of new application programming interfaces. Chief among them is the inclusion of [[.NET Framework 3.0|version 3.0]] of the [[.NET Framework]], which consists of a [[class library]] and [[Common Language Runtime]]. Version 3.0 includes four new major components:<ref>[http://msdn.microsoft.com/winfx/technologies/ .NET Framework 3.0 Technologies], [[Microsoft]] {{webarchive |url=https://web.archive.org/web/20060718172531/http://msdn.microsoft.com/winfx/technologies/ |date=July 18, 2006}}</ref>
* '''[[Windows Presentation Foundation]]''' is a [[user interface]] subsystem and framework based [[vector graphics]], which makes use of [[3D computer graphics]] hardware and [[Direct3D]] technologies. It provides the foundation for building applications and blending application UI, documents, and media content. It is the successor to [[Windows Forms]].
* '''[[Windows Communication Foundation]]''' is a service-oriented messaging subsystem that enables applications and systems to interoperate locally or remotely using [[Web service]]s.
* '''[[Windows Workflow Foundation]]''' provides task automation and integrated transactions using [[workflow]]s. It is the programming model, engine, and tools for building workflow-enabled applications on Windows.
* '''[[Windows CardSpace]]''' is a component that securely stores digital identities of a person, and provides a unified interface for choosing the identity for a particular transaction, such as logging into a website.<ref>{{cite web|url=https://www.wsj.com/articles/SB115456348562125178|title=New Ways to Prove You Are Who You Say You Are Online|first=Jessica E.|last=Vascellaro|work=[[The Wall Street Journal]]|date=August 3, 2006|access-date=March 16, 2016|archive-date=March 10, 2016|archive-url=https://web.archive.org/web/20160310202750/http://www.wsj.com/articles/SB115456348562125178|url-status=live}}</ref>

These technologies are also available for [[Windows XP]] and [[Windows Server 2003]] to facilitate their introduction to and usage by developers and end-users.

There are also significant new development APIs in the core of the operating system, notably the completely re-designed audio, networking, print, and video interfaces, major changes to the security infrastructure, improvements to the deployment and installation of applications ("[[ClickOnce]]" and [[Windows Installer]] 4.0), new device driver development model ("[[Windows Driver Foundation]]"), [[Transactional NTFS#Transactional NTFS|Transactional NTFS]], mobile computing API advancements (power management, [[Tablet PC]] Ink support, [[SideShow]]) and major updates to (or complete replacements of) many core subsystems such as [[Winlogon]] and [[Cryptographic Application Programming Interface|CAPI]].

There are some issues for software developers using some of the graphics APIs in Vista. Games or programs built solely on the Windows Vista-exclusive version of [[DirectX]], version 10, cannot work on prior versions of Windows, as [[DirectX 10]] is not available for previous Windows versions. Also, games that require the features of D3D9Ex, the updated implementation of DirectX 9 in Windows Vista are also incompatible with previous Windows versions.<ref>{{cite web | url=http://www.atomicmpc.com.au/article.asp?CIID=24636 | title=DirectX 10: More harm than good for graphics? | first=Logan | last=Booker | publisher=Maximum Power Computing Atomic | date=September 15, 2005 | access-date=May 28, 2006 | archive-url=https://web.archive.org/web/20060627101625/http://www.atomicmpc.com.au/article.asp?CIID=24636 | archive-date=June 27, 2006  | df=dmy-all }}</ref> According to a Microsoft blog, there are three choices for [[OpenGL]] implementation on Vista. An application can use the default implementation, which translates OpenGL calls into the Direct3D API and is frozen at OpenGL version 1.4, or an application can use an Installable Client [[device driver|Driver]] (ICD), which comes in two flavors: legacy and Vista-compatible. A legacy ICD disables the [[Desktop Window Manager]], a Vista-compatible ICD takes advantage of a new API, and is fully compatible with the Desktop Window Manager.<ref>{{cite web | url=http://blogs.msdn.com/kamvedbrat/archive/2006/02/22/537624.aspx | title=more comments... | first=Kam | last=VedBrat | publisher=MSDN Blogs | date=February 22, 2006 | access-date=May 28, 2006 | archive-date=March 17, 2006 | archive-url=https://web.archive.org/web/20060317221758/http://blogs.msdn.com/kamvedbrat/archive/2006/02/22/537624.aspx | url-status=live }}</ref> At least two primary vendors, [[ATI Technologies|ATI]] and [[NVIDIA]] provided full Vista-compatible ICDs.<ref>{{cite web | url=http://www.khronos.org/developers/library/siggraph2006/OpenGL_BOF/ | title=OpenGL on Vista | first=Neil | last=Trevett | publisher=Khronos Group | year=2006 | access-date=November 9, 2006 | archive-date=September 24, 2006 | archive-url=https://web.archive.org/web/20060924130913/http://www.khronos.org/developers/library/siggraph2006/OpenGL_BOF/ | url-status=live }}</ref> However, [[hardware overlay]] is not supported, because it is considered as an obsolete feature in Vista.

== Visual styles ==
[[File:Vista-visual-styles-comparison.png|thumb|200px|A comparison of the four distinct visual styles included in Windows Vista]]
Windows Vista includes four distinct visual styles:<ref name="WVPG"/>

; Windows Aero
: [[Windows Aero]] requires the Desktop Window Manager and is available in Home Premium and subsequent editions. Windows Aero introduces support for advanced visual effects such as blurred glass translucencies and dynamic glass reflections, Flip and Flip 3D, smooth window animations, and thumbnails on the taskbar. Windows Aero is intended for mid-range to high-end video cards; to enable its features the contents of every open window are stored in video in video memory to facilitate preemptive graphic operations such as [[Page tearing|tearing]]-free movement of windows. As a result, Windows Aero has significantly higher hardware requirements than its predecessors; video cards must support 128&nbsp;MB of memory, [[RGBA color model|32 bits per pixel]], [[DirectX 9]], [[Shader#Pixel shader|Pixel Shader 2.0]], and the new [[Windows Display Driver Model]] (WDDM).
; Windows Vista Standard
: A variant of Windows Aero, but it lacks advanced graphical effects including blurred glass translucencies, dynamic glass reflections, and smooth window animations; it is only included in Windows Vista Home Basic.
; Windows Vista Basic
: A visual style that does not rely on the Desktop Window Manager; as such, it does not feature blurred glass translucencies, dynamic glass reflections, smooth window animations, or taskbar thumbnails. Windows Vista Basic has video card requirements similar to Windows XP, and it is the default visual style of Windows Vista Starter and on systems without support for Windows Aero. Before Windows Vista SP1, machines that failed [[Windows Genuine Advantage]] product license validation would also revert to this visual style.<ref name="HomeBasic">{{cite web |url=http://www.winsupersite.com/showcase/winvista_ff_basic_ux.asp |title=Windows Vista Feature Focus: Windows Vista Basic User Interface |last=Thurrott |first=Paul |date=August 25, 2008 |publisher=[[Penton (company)|Penton]] |work=ITPro Today |archive-url=https://web.archive.org/web/20090222183652/http://www.winsupersite.com/showcase/winvista_ff_basic_ux.asp |archive-date=February 22, 2009 |access-date=September 9, 2022}}</ref>
; Windows Standard/Windows Classic
: This visual style reprises the user interface of [[Windows 9x]], [[Windows 2000]], and [[Windows Server]]. As with previous versions of Windows, this visual style supports custom color schemes, which are collections of color settings. Windows Vista includes four high-contrast color schemes and the default color schemes from [[Windows 98]] (titled "Windows Classic") and [[Windows 2000]]/[[Windows Me]] (titled "Windows Standard").

Windows Vista's Basic and Classic interfaces work with virtually any graphics hardware that supports Windows XP or 2000; accordingly, most discussion around Vista's graphics requirements centers on those for the Windows Aero interface. As of Windows Vista Beta 2, the NVIDIA [[GeForce 6]] series and later, the ATI [[Radeon 9500]] and later, Intel's [[GMA 950]] and later integrated graphics, and a handful of [[VIA chipsets]] and [[S3 Graphics]] discrete chips are supported. Although originally supported, the GeForce FX 5 series has been dropped from newer drivers from NVIDIA.

== Updates ==
Microsoft releases updates such as [[service pack]]s for its Windows operating systems to add features, address issues, and improve performance and stability.

=== Service Pack 1 ===
Windows Vista Service Pack 1 (SP1) was released on February 4, 2008, alongside [[Windows Server 2008]] to [[OEM]] partners, after a five-month beta test period. The initial deployment of the service pack caused a number of machines to continually reboot, rendering the machines unusable.<ref>{{cite web

}}</ref> This temporarily caused Microsoft to suspend automatic deployment of the service pack until the problem was resolved. The synchronized release date of the two operating systems reflected the merging of the workstation and server [[kernel (operating system)|kernels]] back into a single [[source code|code base]] for the first time since [[Windows 2000]]. [[MSDN]] subscribers were able to download SP1 on February 15, 2008. SP1 became available to current Windows Vista users on [[Windows Update]] and the Download Center on March 18, 2008.<ref>{{cite web

A white paper, published by Microsoft on August 29, 2007, outlined the scope and intent of the service pack, identifying three major areas of improvement: reliability and performance, administration experience, and support for newer hardware and standards.<ref>{{cite web|url=https://techcrunch.com/2007/08/30/windows-vista-sp1-gets-officially-announced/|title=Windows Vista SP1 Gets Officially Announced|first=Vince|last=Veneziani|work=[[TechCrunch]]|publisher=[[AOL]]|date=August 30, 2007|access-date=March 16, 2016|archive-date=March 23, 2016|archive-url=https://web.archive.org/web/20160323143242/http://techcrunch.com/2007/08/30/windows-vista-sp1-gets-officially-announced/|url-status=live}}</ref>

Service Pack 1 introduced support for some new hardware and software standards, notably the [[exFAT]] file system,<ref name="sp1whitepaper" /> [[802.11n]] wireless networking, [[IPv6]] over [[VPN]] connections, and the [[Secure Socket Tunneling Protocol]].<ref>{{cite web|url=https://technet.microsoft.com/en-us/library/cc749132(v=ws.10).aspx|title=Overview of Windows Vista Service Pack 1|work=[[Microsoft TechNet|TechNet]]|publisher=[[Microsoft]]|date=February 5, 2008|access-date=March 17, 2016|archive-date=April 1, 2016|archive-url=https://web.archive.org/web/20160401005639/https://technet.microsoft.com/en-us/library/cc749132(v=ws.10).aspx|url-status=live}}</ref>

Booting a system using [[Extensible Firmware Interface]] on [[x64]] systems was also introduced;<ref name="sp1whitepaper" /> this feature had originally been slated for the initial release of Vista but was delayed due to a lack of compatible hardware at the time. Booting from a [[GUID Partition Table]]–based hard drive greater than 2.19&nbsp;TB is supported (x64 only).<ref>{{cite web |url=http://msdn.microsoft.com/en-us/windows/hardware/gg463525 |title=Windows and GPT FAQ |website=[[MSDN]] |publisher=[[Microsoft]] |date=June 15, 2011 |access-date=February 4, 2012 |archive-date=February 7, 2012 |archive-url=https://web.archive.org/web/20120207125205/http://msdn.microsoft.com/en-us/windows/hardware/gg463525 |url-status=live }}</ref><ref>It is possible only when installing from installation DVD of Windows Vista x64 with its service pack 1 integrated.</ref>

Two areas have seen changes in SP1 that have come as the result of concerns from software vendors. One of these is desktop search; users will be able to change the default [[desktop search]] program to one provided by a third party instead of the Microsoft desktop search program that comes with Windows Vista, and desktop search programs will be able to seamlessly tie in their services into the operating system.<ref name="Fried" /> These changes come in part due to complaints from [[Google]], whose [[Google Desktop Search]] application was hindered by the presence of Vista's built-in desktop search. In June 2007, Google claimed that the changes being introduced for SP1 "are a step in the right direction, but they should be improved further to give consumers greater access to alternate desktop search providers".<ref>{{cite web

The [[Group Policy]] Management Console (GPMC) was replaced by the Group Policy Object Editor. An updated downloadable version of the Group Policy Management Console was released soon after the service pack.

SP1 enables support for hotpatching, a reboot-reduction servicing technology designed to maximize uptime. It works by allowing Windows components to be updated (or "patched") while they are still in use by a running process. Hotpatch-enabled update packages are installed via the same methods as traditional update packages, and will not trigger a system reboot.<ref name="technetnotablesp1">{{cite web

; Microsoft Malware Protection Engine patch
: A vulnerability related to Windows Defender that affected the way the Malware Protection Engine operates ({{CVE|2017-0290}}) was reported in May 2017.

== Criticism ==
{{Main|Criticism of Windows Vista}}
Windows Vista received mixed reviews. Criticism targets include protracted development time (5–6 years), more restrictive licensing terms, the inclusion of several technologies aimed at restricting the copying of protected digital media,<ref>{{cite web|url=http://badvista.fsf.org/what-s-wrong-with-microsoft-windows-vista|title=What's wrong with Microsoft Windows Vista?|date=March 6, 2007|access-date=March 24, 2007|last=Sullivan|first=John|publisher=[[Free Software Foundation]]|archive-date=March 22, 2007|archive-url=https://web.archive.org/web/20070322221516/http://badvista.fsf.org/what-s-wrong-with-microsoft-windows-vista|url-status=live}}</ref> and the usability of the new [[User Account Control]] security technology. Moreover, some concerns have been raised about many PCs meeting "Vista Premium Ready" hardware requirements and Vista's pricing.

=== Hardware requirements ===
While in 2005 Microsoft claimed "nearly all PCs on the market today will run Windows Vista",<ref name="Hwreqts2">{{cite web

It has been revealed that an Upgrade copy of Windows Vista can be installed clean without first installing a previous version of Windows. On the first install, Windows will refuse to activate. The user must then reinstall that same copy of Vista. Vista will then activate on the reinstall, thus allowing a user to install an Upgrade of Windows Vista without owning a previous operating system.<ref>{{cite web

=== Digital rights management ===
Windows Vista supports additional forms of [[digital rights management|DRM]] restrictions. One aspect of this is the [[Protected Video Path]], which is designed so that "premium content" from [[HD DVD]] or [[Blu-ray Disc]]s may mandate that the connections between PC components be encrypted. Depending on what the content demands, the devices may not pass premium content over non-encrypted outputs, or they must artificially degrade the quality of the signal on such outputs or not display it at all. Drivers for such hardware must be approved by Microsoft; a revocation mechanism is also included, which allows Microsoft to disable drivers of devices in end-user PCs over the Internet.<ref name="Microsoft-ocp">{{cite web
