Windows 8 build 7989 has been leaked to torrent sites. Screenshots of build 7989 have been released on the BetaArchive forums with the full build string of "7989.winmain.110421-1825.615974c7346f7374", what this means is the build was compiled on April 21, 2011 at 6:25pm.

The new screenshots show a new background and boot screen but apart from that there is no new info on what the actual build contains. It seems all eyes are on Microsoft to see the continued success of Windows after the success they found in Windows 7. Note that this build does not include the new touch UI.
