Windows 8 build 7927 (fbl srv wdacxml)

Windows 8 build 7927 (fbl_srv_wdacxml) is a build of Windows 8, which was uploaded to BetaArchive on 29 August 2011. This build is notable for including Sysinternals and IDW tools by default, along with a copy of Windows Performance Analyzer.

The desktop wallpaper has been changed to a plain dark green background featuring a wordoku puzzle with the leak warning. This wordoku would eventually be solved to form "Start Me Up".

The copyright year in winver was updated from 2010 to 2011. This persisted up to build 8176.

Redpill features
A tool named Redlock can be used to unlock all of the Redpill levels on this build, including the Start screen.

Compared to the earlier build 7899, the Start screen accents are enabled by default and the rendering issues have been fixed. The start screen clock is now black. Some dialogs have been updated to use WPF material:
 * Confirm to run a program (now referred as Windows SmartScreen). It now displays the message that, with the options to prevent it from running or even to delete it. To run this program, click on "More Information" and then on "Run this program and don't prompt me again (not recommended)".
 * Select a program to open a file: The design scheme from Windows XP and later has been dropped.

Bugs

 * The System Reserved partition is shown in Explorer for no apparent reason.

Aero
This build appears to have a slightly broken Windows Aero theme, with only the top portion of the window frame using the blur effect, leaving the side borders transparent.

System Reset
System Reset will say that no valid installation media has been found, even if you have the correct installation media inserted.

Windows Preinstallation Environment

 * Due to this build only being leaked in WIM form, the ISO is packed with the Windows Preinstallation Environment from the Windows 7 RTM build.
