Window$ 7 is the latest version of Microsoft Window$, a series of operating systems produced by Microsoft for use on personal computers, including home and business desktops, laptops, netbooks, tablet PCs and media center PCs.
Unlike its predecessor, which introduced a large number of new features, Window$ 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. Presentations given by Microsoft in 2008 focused on multi-touch support, a redesigned Window$ Shell with a new taskbar, a home networking system called HomeGroup, and performance improvements. Some applications that have been included with prior releases of Microsoft Window$, including Window$ Calendar, Window$ Mail, Window$ Movie Maker, and Window$ Photo Gallery, are not included in Window$ 7; some are instead offered separately as part of the free Window$ Live Essentials suite.
