Windows 8 build 7973 (fbl core2 sid data)

Windows 8 build 7973 (fbl core2 sid data) is a Milestone 3 build of Windows 8. This build was only leaked as an x64 checked/debug version. It bears little difference to the previous build.

Redpill
A version of MetroUnlocker was released on 2019-08-05, unlocking all redpill levels on this build, including the start screen.

The Metro in this build is identical to its alternate compiles. However, MS Help has been removed.

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.
