Windows 7

----
Windows 7 (formerly codenamed Blackcomb and Vienna) is an upcoming version of Microsoft Windows, a series of operating systems produced by Microsoft for use on personal computers, including home and business desktops, laptops, tablet PCs and media center PCs.[2] Windows 7 was released to manufacturing on July 22, 2009,[3] with general retail availability set for October 22, 2009,[4] less than three years after the release of its predecessor, Windows Vista. Windows 7's server counterpart, Windows Server 2008 R2, is slated for release at the same time.

Unlike its predecessor, which introduced a large number of new features, Windows 7 is intended to be a more focused, incremental upgrade to the Windows line, with the goal of being fully compatible with applications and hardware with which Windows Vista is already compatible.[5] Presentations given by the company in 2008 focused on multi-touch support, a redesigned Windows Shell with a new taskbar, a home networking system called HomeGroup,[6] and performance improvements. Some applications that have been included with prior releases of Microsoft Windows, including Windows Calendar, Windows Mail, Windows Movie Maker, and Windows Photo Gallery, will not be included in Windows 7;[7][8] some will instead be offered separately as part of the free Windows Live Essentials suite.
