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

Continuing on with the evolution of Metro starting with build 7973, in many ways, the unlocked features in this build are a middle ground between the early Milestone 2 Metro of builds 7927 to 7963 and the closer to final looks of builds 8032 and 8056. The Start screen now has the "Start" header, along with the Other Programs UI being replaced with the Applications list. The Charms bar now has a clock appear along with it, along with the Settings charm being redesigned, adding some non-functional toggles for the Power, keyboard, and a mysterious toggle called "VanUI".

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.

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.

This build is one of the last to include the ability to use the desktop wallpaper as the logon screen background.

EFI
This build appears to not support hardware with EFI, due to being bundled with an x86 7600 WinPE setup. To try and solve this, copy 7989's install.wim into an x64 7600/7601 WinPE setup, or deploy the image through DISM - this fix does not work for all UEFI configurations.

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.
