Windows 8 is the upcoming release 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. This pre-release version is called “Consumer Preview”, which was released on February 29, 2012.
Windows 8 has been “reimagined from the chipset to the user experience” to connect with the user more. It features the Metro-style interface that is designed for touchscreen input similar to that in Windows Phone and on the Xbox 360. It also adds support for the ARM processor architecture in addition to the previously supported x86 microprocessors from Intel and AMD.
