It was not long ago that an early build of Windows 8 leaked to the Internet. While that build was a bit dated, there now appears to be users who have build 7955 in their hands. While the build has not fully leaked, it is clear that users outside of Microsoft have the build in their possession and winfuture.de has posted up a complete overview of the platform including a logon video.
