==Development==
{{Main|Development of Windows 7}}Originally, a version of Windows codenamed [[List of Microsoft codenames#Windows NT_family|''Blackcomb'']] was planned as the successor to [[Windows XP]] (codename [[List of Microsoft_codenames#Windows NT family|Whistler]]) and [[Windows Server 2003]]. Major features were planned for Blackcomb, including an emphasis on searching and querying data and an advanced storage system named [[WinFS]] to enable such scenarios. However, an interim, minor release, codenamed "[[List of Microsoft codenames#Windows NT family|Longhorn]]" was announced for 2003, delaying the development of Blackcomb.<ref>{{cite web |url= http://www.theregister.co.uk/2001/10/24/gates_confirms_windows_longhorn |title=Gates confirms Windows Longhorn for 2003 |last=Lettice |first=John |date=2001-10-24 |publisher=The Register |accessdate=2008-03-05}}</ref> By the middle of 2003, however, Longhorn had acquired some of the features originally intended for Blackcomb. After three major [[computer virus|viruses]] exploited flaws in Windows operating systems within a short time period in 2003, Microsoft changed its development priorities, putting some of Longhorn's major development work on hold while developing new [[service pack]]s for Windows XP and Windows Server 2003. [[Development of Windows Vista|Development of Longhorn (Windows Vista)]] was also restarted, and thus delayed, in August 2004. A number of features were cut from Longhorn.<ref>{{cite web | title=Microsoft cuts key Longhorn feature | url=http://www.seattlepi.com/business/188339_msftcuts28.html | work=Todd Bishop | publisher=Hearst Seattle Media, LLC | date=August 28, 2004 | accessdate=2009-03-25}}</ref>

The first external release to select Microsoft partners came in January 2008 with [[Development of Windows 7#Milestone 1|Milestone 1]], build 6519.<ref>{{cite web|url=http://www.w7forums.com/windows-7-build-numbers-t58.html|title=Windows 7 Build Numbers|author=Ian Cunningham|date=3 December 2008}}</ref> At [[Professional Developers Conference|PDC]] 2008, Microsoft demonstrated Windows 7 with its reworked [[taskbar]]. Copies of Windows 7 build 6801 were distributed at the end of the conference; however, the demonstrated [[Features new to Windows 7#Taskbar|taskbar]] was disabled in this build.

On December 27, 2008, Windows 7 Beta was leaked onto the Internet via [[BitTorrent (protocol)|BitTorrent]].<ref>{{cite web|url=http://www.osnews.com/story/20703/Windows_7_Beta_1_Leaked |title=OSNews.com |publisher=OSNews.com |date= |accessdate=2009-05-25}}</ref> According to a performance test by [[ZDNet]],<ref>{{cite web|url=http://blogs.zdnet.com/hardware/?p=3236&page=2 |title=Windows 7 beta 1 performance - How does the OS compare to Vista and XP? &#124; Hardware 2.0 &#124; ZDNet.com |publisher=Blogs.zdnet.com |date=2009-01-01 |accessdate=2009-05-25}}</ref> Windows 7 Beta beat both Windows XP and Vista in several key areas; including boot and shutdown time and working with files, such as loading documents.

===Goals===
[[Bill Gates]], in an interview with'' [[Newsweek]]'', suggested that this version of Windows would "be more user-centric".<ref name="gates">{{cite web|url=http://www.msnbc.msn.com/id/16934083/site/newsweek/page/4/print/1/displaymode/1098/|title=Bill Gates on Vista and Apple's 'Lying' Ads|author=Steven Levy|date= 3 February 2007}}</ref> Gates later said that Windows 7 would also focus on performance improvements.<ref name="gates2">{{cite web|url=http://www.microsoft.com/presspass/exec/billg/speeches/2008/05-07japanwdlc.mspx|title=Bill Gates: Japan—Windows Digital Lifestyle Consortium|author=Bill Gates|date=12 May 2007}}</ref> [[Steven Sinofsky]] later expanded on this point, explaining in the ''Engineering Windows 7'' blog that the company was using a variety of new tracing tools to measure the performance of many areas of the operating system on an ongoing basis, to help locate inefficient code paths and to help prevent performance regressions.<ref>{{cite web |url=http://blogs.msdn.com/e7/archive/2008/12/15/continuing-our-discussion-on-performance.aspx |title=Continuing our discussion on performance |last=Sinofsky |first=Steven |authorlink=Steven Sinofsky |date=15 December 2008 |accessdate=2008-12-18 |work=Engineering Windows 7 |publisher=Microsoft }}</ref>

==Features==
===New and changed features===
[[Image:Action Center on Windows 7.png|thumb|right|The new [[Action Center]], which replaces [[Windows Security Center]]]]
{{Main|Features new to Windows 7}}
Windows 7 includes a number of new features, such as advances in touch and [[handwriting recognition]], support for [[VHD (file format)|virtual hard disks]], improved performance on [[multi-core]] processors,<ref>{{cite web|url=http://www.windowsvienna.com/windows-7-takes-more-advantage-of-multi-core-cpus-a24.html |title=Windows 7 Takes More Advantage of Multi-Core CPUs - Windows 7 |publisher=Windowsvienna.com |date= |accessdate=2009-05-25}}</ref><ref>{{cite web|url=http://blogs.zdnet.com/microsoft/?p=1612 |title=Windows 7 to get parallel-processing tweaks &#124; All about Microsoft &#124; ZDNet.com |publisher=Blogs.zdnet.com |date=2008-09-30 |accessdate=2009-05-25}}</ref><ref>{{cite web|url=http://www.pctipsbox.com/windows-7-to-get-parallel-processing-tweaks/ |title=Windows 7 to get parallel-processing tweaks &#124; PC Tips |publisher=Pctipsbox.com |date=2008-10-05 |accessdate=2009-05-25}}</ref><ref>{{cite web|url=http://vista.blorge.com/2008/09/30/windows-7-enters-parallel-universe/ |title=Windows 7 enters parallel universe |publisher=Vista.Blorge |date=2008-09-30 |accessdate=2009-05-25}}</ref> improved [[booting|boot]] performance, [[DirectAccess]], and [[kernel (computing)|kernel]] improvements.

Many new items have been added to the [[Control Panel (Windows)|Control Panel]], including [[ClearType]] Text Tuner, Display Color Calibration Wizard, [[Microsoft_Gadgets#Desktop_gadgets|Gadgets]], Recovery, Troubleshooting, Workspaces Center, Location and Other Sensors, Credential Manager, Biometric Devices, System Icons, and Display.<ref>[http://www.thinknext.net/archives/2150 ThinkNext.net: Screenshots from a blogger with Windows 7 M1]</ref> [[Windows Security Center]] has been renamed to Windows Action Center (Windows Health Center and Windows Solution Center in earlier builds), which encompasses both [[computer security|security]] and maintenance of the computer.

The taskbar has seen the biggest visual changes, where the Quick Launch toolbar has been replaced with pinning applications to the taskbar. Buttons for pinned applications are integrated with the task buttons. These buttons also enable the ''Jump Lists'' feature to allow easy access to common tasks.<ref name="Softpedia04Nov08"> {{cite web|url = http://news.softpedia.com/news/Windows-7-User-Interface-The-Superbar-Enhanced-Taskbar-97143.shtml|title = Windows 7 User Interface&nbsp;– The Superbar (Enhanced Taskbar)|accessdate = 2008-11-12|last = Softpedia|authorlink = |year = 2008|month = November}}</ref> The revamped taskbar also allows the reordering of taskbar buttons. To the far right of the system clock is a small rectangular button that serves as the ''Show desktop'' icon. This button is part of the new feature in Windows 7 called ''Aero Peek''. Hovering over this button makes all visible windows transparent for a quick look at the desktop.<ref>[http://money.cnn.com/news/newsfeeds/siliconalley/big-tech/2008_12_windows_7_some_minor_improvements_no_game_changer_msft.html Windows 7: Some Minor Improvements, No Game Changer]</ref> In touch-enabled displays such as touch screens, tablet PCs, etc., this button is slightly wider to accommodate being pressed with a finger.<ref>[http://blogs.msdn.com/e7/archive/2009/03/25/touching-windows-7.aspx Touching Windows 7 (Engineering Windows 7 Blog)]</ref> Clicking this button minimizes all windows, and clicking it a second time restores them. Additionally, there is a feature named ''Aero Snap'', that automatically maximizes a window when it is dragged to either the top or left/right edges of the screen.<ref>{{cite web|url=http://blogs.msdn.com/e7/archive/2009/03/17/designing-aero-snap.aspx|title=Engineering Windows 7 : Designing Aero Snap|publisher=Steven Sinofsky/Microsoft|accessdate=2009-06-08}}</ref> This also allows users to snap documents or files on either side of the screen to compare them. When a user moves windows that are maximized, the system restores their previous state automatically. This functionality is also accomplished with keyboard shortcuts.
Unlike in [[Windows Vista]], window borders and the taskbar do not turn opaque when a window is maximized with [[Windows Aero]] applied. Instead, they remain translucent.

===Removed features===
{{Main|Features removed from Windows 7}}

A number of capabilities and certain programs that were a part of [[Windows Vista]] are no longer present or have been changed, resulting in the removal of certain functionality. Some notable Windows Vista features and components have been replaced or removed in Windows 7, including the classic [[Start Menu]] user interface, [[Windows Ultimate Extras]] and [[InkBall]]. Four applications bundled with Windows Vista &mdash; [[Windows Photo Gallery]], [[Windows Movie Maker]], [[Windows Calendar]]<ref>{{cite web|url=http://download.live.com/windows7|title=Finding your applications in Windows 7|accessdate=2009-10-23|date=2009-10-22|publisher=Microsoft|author=Windows Live team}}</ref> and [[Windows Mail]] &mdash; are not included with Windows 7, but are instead available for free in a separate package called [[Windows Live Essentials]].

==Antitrust regulatory attention==
As with other Microsoft operating systems, Windows 7 is being studied by United States federal regulators who oversee the company's operations following the 2001 ''[[United States v. Microsoft]]'' settlement. According to status reports filed, the three-member panel began assessing prototypes of the new operating system in February 2008. [[Michael Gartenberg]], an analyst at [[Jupiter Research]] said that, "[Microsoft's]<!--The word "Microsoft" is in square brackets here because it was inserted into the quote to replace the unclear pronoun "Their " in this context. Please do not wikify this as it would make it look like the word "Microsoft" was in the original quote which is not the case --> challenge for Windows 7 will be how can they continue to add features that consumers will want that also don't run afoul of regulators."<ref> {{cite web|url = http://www.computerworld.com/action/article.do?command=viewArticleBasic&articleId=9068339&taxonomyId=14&intsrc=kc_top|title = Windows 7 eyed by antitrust regulators|accessdate = 2008-03-19|last = Keizer|first = Gregg F.|authorlink = |year = 2008|month = March}}</ref>
