Windows 7 is a major release of the Windows NT operating system developed by Microsoft. It was released to manufacturing on July 22, 2009, and became generally available on October 22, 2009.[9] It is the successor to Windows Vista, released nearly three years earlier. It remained an operating system for use on personal computers, including home and business desktops, laptops, tablet PCs and media center PCs, and itself was replaced in November 2012 by Windows 8, the name spanning more than three years of the product. Until April 9, 2013, Windows 7 RTM provided content such as security updates, software updates, PC driver updates and technical support, after which installation of Service Pack 1 is required for users to receive support and updates. Windows 7's server counterpart, Windows Server 2008 R2, was released at the same time. The last supported version of Windows based on this operating system was released on July 1, 2011, entitled Windows Embedded POSReady 7. On January 12, 2016, Microsoft ended support for Internet Explorer versions older than Internet Explorer 11 on Windows 7.[10][11][12] Extended support ended on January 14, 2020, over ten years after the release of Windows 7, after which the operating system ceased receiving further support or security updates to most users, and all PCs that blocks Windows Update on Windows 7 versions newer than KB4499164 released in May 2019 displays a full-screen upgrade warning notification with an information page link starting from January 15, 2020. A support program is currently available for enterprises, providing security updates for Windows 7 for up to four years since the official end of life.[13] However, Windows Embedded POSReady 7, the last Windows 7 variant, continued to receive security updates until October 2021.

Windows 7 was intended to be an incremental upgrade to Microsoft Windows, addressing Windows Vista's poor critical reception while maintaining hardware and software compatibility. Windows 7 continued improvements on Windows Aero (the user interface introduced in Windows Vista) with the addition of a redesigned taskbar that allows applications to be "pinned" to it, and new window management features. Other new features were added to the operating system, including libraries, the new file-sharing system HomeGroup, and support for multitouch input. A new "Action Center" interface was also added to provide an overview of system security and maintenance information, and tweaks were made to the User Account Control system to make it less intrusive. Windows 7 also shipped with updated versions of several stock applications, including Internet Explorer 8, Windows Media Player, and Windows Media Center.

Unlike Vista, Windows 7 received critical acclaim, with critics considering the operating system to be a major improvement over its predecessor because of its improved performance, its more intuitive interface (with particular praise devoted to the new taskbar), fewer User Account Control popups, and other improvements made across the platform. Windows 7 was a major success for Microsoft; even before its official release, pre-order sales for the operating system on the online retailer Amazon.com had surpassed previous records. In just six months, over 100 million copies had been sold worldwide, increasing to over 630 million licenses by July 2012. By January 2018, Windows 10 surpassed Windows 7 as the most po[CENSORED]r version of Windows worldwide;[14] and by May 2020, Windows 10 surpassed Windows 7 as the most po[CENSORED]r version of Windows in China.[15] As of December 2021, 12.76% of traditional PCs running Windows are running Windows 7 (and thus 3.4% of all devices across platforms).[16] It still remains po[CENSORED]r in countries such as Syria, China, India, and Venezuela.[17][18][19]

Development history

Originally, a version of Windows codenamed "Blackcomb" was planned as the successor to Windows XP and Windows Server 2003 in 2000. 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 "Longhorn," was announced for 2003, delaying the development of Blackcomb.[20] By the middle of 2003, however, Longhorn had acquired some of the features originally intended for Blackcomb. After three major malware outbreaks—the Blaster, Nachi, and Sobig worms—exploited flaws in Windows operating systems within a short time period in August 2003,[21] Microsoft changed its development priorities, putting some of Longhorn's major development work on hold while developing new service packs for Windows XP and Windows Server 2003. Development of Longhorn (Windows Vista) was also restarted, and thus delayed, in August 2004. A number of features were cut from Longhorn.[22] Blackcomb was renamed Vienna in early 2006,[23] and was later canceled in 2007 due to the scope of the project.[24]

When released, Windows Vista was criticized for its long development time, performance issues, spotty compatibility with existing hardware and software at launch, changes affecting the compatibility of certain PC games, and unclear assurances by Microsoft that certain computers shipping with XP before launch would be "Vista Capable" (which led to a class-action lawsuit), among other critiques. As such, the adoption of Vista in comparison to XP remained somewhat low.[25][26][27] In July 2007, six months following the public release of Vista, it was reported that the next version of Windows would then be codenamed Windows 7, with plans for a final release within three years.[28][29] Bill Gates, in an interview with Newsweek, suggested that Windows 7 would be more "user-centric".[30] Gates later said that Windows 7 would also focus on performance improvements.[31] 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.[32] Senior Vice President Bill Veghte stated that Windows Vista users migrating to Windows 7 would not find the kind of device compatibility issues they encountered migrating from Windows XP.[33] An estimated 1,000 developers worked on Windows 7. These were broadly divided into "core operating system" and "Windows client experience", in turn organized into 25 teams of around 40 developers on average.[34]

In October 2008, it was announced that Windows 7 would also be the official name of the operating system.[35][36] There has been some confusion over naming the product Windows 7,[37] while versioning it as 6.1 to indicate its similar build to Vista and increase compatibility with applications that only check major version numbers, similar to Windows 2000 and Windows XP both having 5.x version numbers.[38] The first external release to select Microsoft partners came in January 2008 with Milestone 1, build 6519.[39] Speaking about Windows 7 on October 16, 2008, Microsoft CEO Steve Ballmer confirmed compatibility between Windows Vista and Windows 7, indicating that Windows 7 would be a refined version of Windows Vista.[40]

At PDC 2008, Microsoft demonstrated Windows 7 with its reworked taskbar.[41] On December 27, 2008, the Windows 7 Beta was leaked onto the Internet via BitTorrent.[42] According to a performance test by ZDNet,[43] 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. Other areas did not beat XP, including PC Pro benchmarks for typical office activities and video editing, which remain identical to Vista and slower than XP.[44] On January 7, 2009, the x64 version of the Windows 7 Beta (build 7000) was leaked onto the web, with some torrents being infected with a trojan.[45][46] At CES 2009, Microsoft CEO Steve Ballmer announced the Windows 7 Beta, build 7000, had been made available for download to MSDN and TechNet subscribers in the format of an ISO image.[47] The stock wallpaper of the beta version contained a digital image of the Betta fish.[48]

The release candidate, build 7100, became available for MSDN and TechNet subscribers, and Connect Program participants on April 30, 2009. On May 5, 2009, it became available to the general public, although it had also been leaked onto the Internet via BitTorrent.[49] The release candidate was available in five languages and expired on June 1, 2010, with shutdowns every two hours starting March 1, 2010.[50] Microsoft stated that Windows 7 would be released to the general public on October 22, 2009, less than three years after the launch of its predecessor. Microsoft released Windows 7 to MSDN and Technet subscribers on August 6, 2009.[51] Microsoft announced that Windows 7, along with Windows Server 2008 R2, was released to manufacturing in the United States and Canada on July 22, 2009. Windows 7 RTM is build 7600.16385.090713-1255, which was compiled on July 13, 2009, and was declared the final RTM build after passing all Microsoft's tests internally.[52]
