Windows 8 unidentified December 2011 build

Several screenshots of an unidentified Windows 8 build from December 2011 were shown off by Windows news website WinUnleaked.tk. Unlike other builds that weren't publicly released officially by Microsoft, this build does feature Metro apps (although PaintPlay alone was brought back from build 8102.101). The Aero Lite (Windows Basic) theme has been updated. The build also notably reuses the PC Settings app icon from the Developer Preview instead of the newer variant from build 8172.
