Windows 8 is the next version of Microsoft Windows, a series of operating systems produced by Microsoft for use on personal computers, including home and business desktops, laptops, Microsoft Tablet PCs, and Home theater PCs. According to unofficial sources, the release date for Windows 8 has been set for October 2012, three years after the release of its predecessor, Windows 7. Windows 8's server counterpart, Windows Server 2012, is in development concurrently with Windows 8. The most recent official pre-release version of Windows 8 is the Release Preview, which was released on May 31, 2012.
Unlike Windows 7, which was intended to be a more focused, incremental upgrade to the Windows line, Windows 8 has been "reimagined from the chipset to the user experience" to connect more with the user. It features the Metro interface that is designed for touchscreen input similar to that in Windows Phone and on the Xbox 360. A version of Windows 8, called Windows RT, also adds support for the ARM processor architecture in addition to the previously supported microprocessors from Intel and AMD.
