Microsoft releases Windows 8 Developer Preview

This is a detailed preview of the next major release of Windows, code-named "Windows 8". You want to check the release notes on this, you cannot upgrade from Windows 7 so if you have an extra computer and want to preview Windows 8, here is your first chance!

Windows 8 is designed to be the first Windows client to support systems on a chip (SoC) architectures, including ARM, and since it will be pre-installed on a range of next generation devices, it will also feature Metro, a NUI + GUI interface on the surface combined with a new application platform under-the-hood designed to enable the creation of immersive experiences.
