This is the most recent publicly available version of Microsoft Windows. It is 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, 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. These series of classes will provide the capabilities to install, maintain, and support the Windows 7 release.
