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, which makes it quite an interesting bug.

Charm bar
The charm bar can be unlocked by using MetroFetro's Metro unlocker. This unlocker installs build 8102's product policy (through several registry keys) and shsxs.dll. After applying this unlocker normal operation of the OS is not possible since Explorer.exe enters a crash loop. When booting in safe-mode, however, the newly unlocked charm bar can be witnessed. The charm bar gives access to working search functionality. Note the grid-like icon in the charm bar; this is the 'Switcher' which was also seen in early Windows 8 concepts.

It is interesting to note that besides the charm bar, a `Start menu` process is running in the background. Whenever the charm bar is enabled using above described method, any attempt to open start will result in the Explorer process crashing. Additionally, the charm bar's settings panel shows an option with the name 'VanUI', a code-name for the not yet implemented functionality.

Start screen
BetaWiki Discord member Distort managed to unlock the start screen of this build.
