Windows 7 Full Version Free Download By Collection Of Software

Windows 7 is a personal computer operating system developed by Microsoft, a version of Windows NT. Development of Windows 7 occurred as early as 2006 under the code name "Black comb." Windows 7 was released to manufacturing on July 22, 2009, and became generally available on October 22, 2009, less than three years after the release of its predecessor,Windows Vista. Windows 7's server counterpart, Windows Server 2008 R2, was released at the same time.

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 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 Home Group, 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. 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 task bar), 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 Amazon.com 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 Net Applications, making it the most widely used version of Windows.
