RTM indicates the code is now signed off and available for mass production for mass distribution, that just happened to Windows 7 today. The Operating System is the latest client OS from Microsoft with promises of security, feasibility, productivity and more, ever! Windows 7 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, netbooks, tablet PCs and media center PCs. Windows 7 has general retail availability set for October 22, 2009, 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.
