Redpill
A version of MetroUnlocker was released on 2019-05-10, unlocking all redpill levels on this build, including the start screen.

The unlocked features are notable for being significantly different compared to later builds like 8056 or 8102, including the Start screen using a betta fish pattern, the Charms bar resembling early Windows 8 concept art compared to the look that was standardized with build 8032, and more. Interestingly, in this build, it is already possible to change the accent color of the start screen, however there are only 2 colors available. To do this, open regedit, go to  and create a DWORD named   and set it's value to 1. Logoff and logon again, the start screen will be a different blue gradient.

Compared to later builds, the Start screen also works without Desktop Window Manager. However, it is very unstable as a result.

When the "Share" button from the charms bar is clicked, a file called shrscr.png is created in the %temp% folder, with a cat and text saying "U can haz no pix" on the top and "GIMME FISH" along a number on the bottom. The "U can haz no pix" is probably a reference to the strict NDA that existed during Windows 8's development, implying no pictures of the build can be shared.

EFI
This build appears to not support hardware with EFI, due to being bundled with an x86 7600 WinPE setup. To solve this, copy 7989's install.wim into an x64 7600/7601 WinPE setup, or deploy the image through DISM.

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. In this build however, the bug does not occur if Redpill is unlocked.
