Windows 8 build 8056 (fbl grfx dev1)

Windows 8 build 8056 (fbl grfx dev1) is a pre-Developer Preview build of Windows 8. This build was leaked on September 19, 2015 by OSBetaArchive.

Screenshots of a pseudo-localized version were revealed by gus33000 on BetaArchive Discord on November 7, 2018 and the full build later leaked as an unstaged compilation (with both English and pseudo-localization languages) on February 17, 2020.

Redpill
A program called Redlock is available to unlock all Redpill levels, thus unlocking the entire Metro interface, including the Start screen.

A few changes have occurred since build 8032, mainly focusing on stability and cosmetic updates. Many graphical issues and oddities seen with 8032, including leftover icons from older builds and issues with the graphics and fonts for the tiles, has been fixed, and Metro itself is much more stable. The gradient effect for the background color of the Metro login screen and the Start screen has been removed and the size of the tiles has shrunk. The search pane's close button has also been removed.

When the Share option from the Charms bar is chosen while on the Start screen, it will display "MoGo can't share this, but Windows can share a screenshot instead", hinting as "MoGo" being the codename for the Start screen.

Apps included

 * Immersive Remote Desktop Connection
 * Immersive Control Panel
 * A non-functional early version of the Store
 * Immersive IE

Hardware compatibility
To install or run this build in VMware Workstation 15 or newer, you must set the hardware compatibility to versions 8.x or 9.x; otherwise, a partially garbled system crash message will occur.

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

Another quirk with Intel drivers is that Windows Vista drivers will work if you install this build on a computer that originally had Windows Vista. Before starting the installation, right click the exe and select properties. Click on compatibility and set it to Windows Vista Service Pack 2. Apply and then run the exe normally and you should have working Intel graphics.

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.

User logon error
If you're running this build on certain hardware (most likely newer hardware, such as the HP 15-f233wm), you'll come across that Windows cannot log you in after installing. Using the current BIOS date and the BIOS date of 2011-07-27 produces the error, ruling out that as the issue. To fix this issue, restart Windows and press F8 to access advanced boot options. Chose Safe Mode with Networking and Windows should boot. Go to the start menu and search for regedit, right click that, and run as administrator. Navigate to "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList". Go to the bottom most profile and select it. Once in, double click on State and set its value to 0. Double click on RefCount and also set its value to 0. Restart Windows and you should be in. If you have a .bak profile as well, then rename the profile with no extension as "S-1-5-21-4118428-131-491-1.b" (Sample profile. Keep the name the same, just add .b). Take the one named .bak and remove the extension. Rename the .b profile to .bak. Once done, perform the changes above.

Note: This error may not always appear when clean installing this build.

User Account Control bug
User Account Control will pop up when you change the Windows settings, even if it is set to not notify you when changing those.

Compatibility
Unlike build 8102, 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.

eMMC drive support
This build is likely the first Windows 8 build to support eMMC drives. Installation runs normal. If you install this build on touchscreen devices, it will have touchscreen drivers working out of the box, compared to Windows 7 where support for out of box touchscreen was non-existent without installing a driver.

Device setup
Device setup, if it appears on login, may show up in a broken window.
