Windows 7 is a series of operating systems produced by Microsoft for use on personal computers, including home and business desktops, laptops, notebooks, tablet PCs, and media centre PCs. Windows 7 was released to manufacturing on 22 July 2009 and reached general retail availability worldwide on 22 October 2009.
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.
