Earlier this month, Microsoft has announced that the Windows 8 Developer Preview will be available for download. Now there are 2 versions available for download; the 64-bit and 32-bit versions, both only available in English. Also available for download is the Live SDK, providing a set of controls and APIs that enable applications to integrate Single Sign On (SSO) with Windows Live ID and to access information from SkyDrive, Hotmail and Windows Live Messenger.

Just choose the right version on the basis of your configuration.
