Windows 7 is the current release of Microsoft
Windows, a series of operating
systems produced by Microsoft for use on personal computers,
including home and business desktops,
laptops, netbooks, tablet PCs, and media center PCs. Windows
7 was released to manufacturing on July 22, 2009, and reached general retail
availability worldwide 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.
Unlike Windows Vista, which introduced a large number of new
features, Windows 7 was intended to be a more focused, incremental upgrade to
the Windows line, with the goal of being compatible with applications and
hardware with which Windows Vista was already compatible. Presentations given by Microsoft in
2008 focused on multi-touch support, a redesigned Windows shell with a new taskbar, referred to as the Superbar,
a home networking system called HomeGroup, and
performance improvements. Some standard applications that have been included
with prior releases of Microsoft Windows, including Windows Calendar, Windows Mail, Windows Movie Maker, andWindows Photo
Gallery, are not included in Windows 7; most
are instead offered separately at no
charge as part of the Windows Live Essentials suite.
