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 developed 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.

Timebomb
Unlike older builds and even a few newer builds, it has a working timebomb even after installing with current date, and it doesn't get nulled after disabling SPP. That also means you will be able to change the wallpaper on any date.

Intel HD Graphics
Like most pre-DP builds, installing latest Intel HD Graphics driver will make the screen blink, making it unusable unless you stop DWM. Using an 2013 or older driver will fix this issue.

Drivers
On Windows 7-designed tablets/laptops, even if newer than 2011, this build has touch screen, audio and battery drivers working out of the box.

Compatibility
Unlike the official Developer Preview, this build can run the latest version of Chrome and other programs without trouble. NET Framework 4.5 is incomplete and unable to run programs that needs it.

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