Windows 8 build 7880

Windows 8 build 7880 is a build of Windows 8. Images of this build were posted to the BetaWiki Discord server on 2 June 2020, and the build itself was then leaked to BetaArchive six days later on 8 June 2020.

File History
Introduced File History, then known as History Vault.

Aero and DWM
DWM now uses a software-rendering fallback rather than a hardware-rendering one. The Aero Basic theme is no longer enabled by default, however it can still be enabled.

Protogon
This build has an early implementation of the ReFS file system, at this time known as Protogon.

Blue screen of death

 * This build includes an update to the bugcheck screen. However it is mostly similar to the previous builds.


 * You can see the updated blue screen of death while attempting to open Media center, as it will crash the system with stop code.

Immersive features
Immersive Shell and Metro in general has greatly evolved since build 7850. The Metro Horizon has been removed, although a space for it still exists in the start screen, as well as its resources and DirectUI UIFILEs. Tiles are now icon-aware, and right-clicking on a tile shows a menu with several options - "Move to Other View" being among them, although this does nothing when clicked. In fact, all of the options bar the "Open" option (which opens the app without actually entering the desktop) - including such items as "Uninstall" and "Resize" - either do nothing or show an error when clicked. File search has been added, with a different UI to build 7875, although it does not seem to work. The search suggestions in the start screen now use blue text for their first letter. The Blue Screen of Death now supports VBE2 at all times (7850 only supported it during boot) and uses a smooth font - also not covering the entire screen in certain resolutions - but otherwise is identical to Windows 7.

The Windows Runtime has far more classes than in 7850, with more than a dozen WinMD files compared to 7850's one. Pattern logon is available if you set  in   to 1, however there's no option to use it on the login screen.

Bugs and quirks

 * The messages shown when the Setup is starting or restarting the computer are cut off.
 * This build uses the Arial font for the title bar and watermark because of a typo in the  and   files.
 * When right clicking the desktop, it can take several seconds for the context menu to open.

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.

Aero Glass in Home Basic SKU
The Home Basic SKU doesn't support Aero Glass borders by default, but it can be enabled by clicking on "Windows 7 Standard" color scheme in Window Color and Appearance dialog from the Display control panel item.

Media Center system crash
There's a chance you can encounter a bugcheck with stop code  if you open Windows Media Center on this build.
