{{#REDIRECT [[Windows 7}}#Development history]]

'''Development of [[Windows 7]]''' began when [[Windows Vista]] was released. Milestone 1, Milestone 2, and Milestone 3 were sent to Microsoft's partners in 2008. In October 2008, Microsoft gave build 6801 to PDC attendees and a public beta was released in January 2009.

The release candidate was available from April 30, 2009 for MSDN and Technet subscribers, and was released to the public on May 5, 2009. The final build of Windows 7 was released to manufacturing on July 22, 2009;<ref>{{cite web |url=http://arstechnica.com/microsoft/news/2009/07/microsoft-windows-7-is-done-on-its-way-to-manufacturers.ars |title=Microsoft: Windows 7 is done, on its way to manufacturers |last=Protalinski |first=Emil |date=2009-07-22 |publisher=Ars Technica |accessdate=2009-07-22}}</ref> Technet and MSDN subscribers were able to download it on August 6. On October 22, the operating system was made generally available for public purchase.

==History==

In 2000, Microsoft was planning to follow up [[Windows XP]], and its server counterpart, [[Windows Server 2003]] (both codenamed ''Whistler''), with a major new release of Windows, [[Microsoft code names|codenamed]] ''Blackcomb'' (both codenames refer to the [[Whistler-Blackcomb]] resort). This new version was, at that time, scheduled for a 2005 release.<ref>[http://www.wininsider.com/news/?226 Microsoft pushes back Blackcomb to 2005]</ref><ref>[http://news.cnet.com/2100-1001-966174.html .Net Server: Three delays a charm?]</ref>

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. In this context, a feature mentioned by Microsoft co-founder Bill Gates for Blackcomb was "a pervasive typing line that will recognize the sentence that [the user is] typing in."<ref>{{cite web |url=http://www.microsoft.com/presspass/exec/billg/speeches/2000/07-12pdc.aspx |title = Professional Developers Conference Remarks |last=Gates |first=Bill |authorlink=Bill Gates |publisher=[[Microsoft|microsoft.com]] |date = 2000-07-12 |accessdate=2008-03-05}}</ref>

Later, Blackcomb was delayed, and an interim, minor release, codenamed "Longhorn" (named for the Longhorn Tavern between the resorts), was announced for a 2003 release.<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, including [[WinFS]], the [[Desktop Window Manager]], and new versions of system components built on the [[.NET Framework]]. After the 2003 "Summer of Worms", where three major viruses − [[Blaster (computer worm)|Blaster]], [[Sobig (computer worm)|Sobig]], and [[Welchia]] − exploited flaws in Windows operating systems within a short time period, Microsoft changed its development priorities, putting some of Longhorn's major development work on hold in order to develop new service packs for Windows XP and [[Windows Server 2003]]. [[Development of Windows Vista|Development of Longhorn]] was also "reset" in September 2004.
