Windows 8 build 9200 (win8 rtm)

Windows 8 was the first version of Microsoft Windows operating system to have a major change mainly in User Interface. It introduced the new 'Metro' interface which included full-screen applications (called Windows Store Applications) which were aimed mainly for tablet-PC users, running on a new developed subsystem/layer over Win32 called WinRT. The change included too the Start Screen which replaced the old Start Menu in Windows 7 and older versions of Windows.
