Windows 7 is a personal computer operating system developed by microsoft Windows 7 was primarily intended to be an incremental upgrade to the operating system, intending to address criticisms faced by its predecessor, Windows Vista (such as performance improvements), whilst maintaining compatibility with hardware and software designed for Vista. While retaining a similar appearance to Vista, 7's interface was streamlined, with the addition of a redesigned 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 provide an overview of system security and maintenance information, and tweaks were made to the User Account Control system to make it less intrusive. 7 also shipped with updated versions of several stock applications, including Internet Explorer, Windows Media Player, and Windows Media Center.
In contrast to Vista, Windows 7 was generally praised by critics, who considered the operating system to be a major improvement over its predecessor due to its increased 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 prior to its official release, pre-order sales for 7 on the online retailer had surpassed the record set by Harry Potter and the Deathly Hallows. In just six months, over 100 million copies had been sold worldwide, increasing to over 630 million licenses by July 2012, and a market share of 50.06% as of May 2014 according to making it the most widely used version of Windows
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.[10] By the middle of 2003, however, Longhorn had acquired some of the features originally intended for Blackcomb. After three major viruses, the Blaster,Sober, and Sobig worms, 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 newservice packs for Windows XP and Windows Server 2003. Development of was also restarted, and thus delayed, in August 2004. A number of features were cut from Longhorn.[11] Blackcomb was renamed Vienna in early
When released, Windows Vista was criticized for its long development time, performance issues, its spotty compatibility with existing hardware and software on launch, changes affecting the compatibility of certain PC games, and unclear assurances by Microsoft that certain computers shipping with XP prior to launch would be "Vista Capable" (which led to a class action lawsuit), among other critiques. As such, adoption of Vista in comparison to XP remained somewhat low.[13][14][15] In July 2007, six months following the public release of Vista, it was reported that the next version of Windows would now be codenamed Windows 7, with plans for a final release within three years.[16][17] Bill Gates, in an interview with Newsweek, suggested that Windows 7 would be more "user-centric"
