Windows 8 build 8056 (fbl grfx dev1)

Windows 8 build 8056 is a pre-Developer Preview build of Windows 8. It leaked on 2015-09-19 and was leaked by osbetaarchive.

MetroFetro has released a start screen unlocker, containing a shsxs.dll for this build (apparently a modified 8102 version), unlocking all redpill levels, thus unlocking the entire Metro interface, including the start screen. The unlocker has received criticism for its methods of operation (disabling the Software Protection Service to import in 8102's product policy) and perceived laziness with the modifications to shsxs.dll. However, as of 2019, it is the only public utility that will completely unlock all redpill levels, including the start screen. Apps included:
 * Immersive Remote Desktop Connection
 * Immersive Control Panel
 * Immersive Store.
 * Immersive IE (the initial version of the utility did not unlock it, with a later version being released that used 8102's Immersive Browser files to unlock it on x86 builds. A modified version posted by Windows OS was later released, using 8056's Immersive Browser files instead of 8102's.)

Interestingly, changing the color of start screen already is possible, unlike 8102.

Metro UI
After using MetroUnlocker, the full Metro interface is available for use. This build still uses the start button from Windows 7, however when the cursor is placed in the lower left corner, the charm bar appears. The charm bar is not exactly the same as the one from 8102. When the Share option from the Charm bar is chosen while on start screen, it will display "MoGo can't share this, but Windows can share a screenshot instead", hinting as "MoGo" being the codename for Start Screen.

Psudeo Localized version
Screenshots were leaked by gus33000 on BetaArchive Discord on 2018-11-07. As of 2024, it is unleaked, unlike the regular build.
