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 to 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.

Fixes
The quirk that the last word is cut off in some setup messages has been fixed in this build.

System Reserved
The System Reserved partition appears in File 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. This is perhaps caused by the quirk with the Windows PE listed underneath.

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.
 * As a result of that, the System Reset option does not appear in Windows RE when launching it from the installation media.
 * Also, the "Repair your computer" option is missing in the advanced boot options.

Setup/Redpill
At the end of the second stage of clean setup and the third and fourth stages of upgrade setup, as well as the final stage of redpilling, the startup sound plays, but will get cut after ¾ due to the following restart of the computer.
