New features and changes[edit | edit source]

This is the first known build to feature a software-based implementation of the DWM rasterization functionalities, which eliminates the 3D acceleration hardware requirement needed for Aero effects.

Immersive features[edit | edit source]

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 and Windows Boot Manager now support VBE 2.0 at all times (7814 through 7878 only supported VBE 2.0 during boot) and use a smooth font - also not covering the entire screen in certain resolutions - but otherwise is identical to Windows 7.

The Windows Runtime is more mature in this build than build 7850. Pattern logon is available if the EnablePatternLogonForInternalTesting DWORD in the HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion key is set to 1. Like the previous build, there is no option to use it on the login screen.

Bugs and quirks[edit | edit source]

General[edit | edit source]

  • Shutdown or restart will cause a softlock when running this build in VMware Workstation 15 or newer. This can be worked around by using the host's Power menu.

Setup[edit | edit source]

  • The last word of status messages shown when starting Setup and before the computer reboots into OOBE is cut off.
  • Attempting to select a network type will result in a driver unload bugcheck. To work around this issue, remove or disable any network adapters before booting into OOBE.

Themes[edit | edit source]

  • The title bar and watermark uses the Arial font due to a typo in the aero.msstyles and aerolite.msstyles files.
  • Only the top portion of the window frame is blurred when using the Windows Aero theme, leaving the side borders transparent.
  • The Windows Basic and the High Contrast themes do not render properly due to the enforcement of the DWM Aero theme.

Shell[edit | edit source]

  • The desktop context menu can take several seconds to open.
  • This build uses both the old and the new language switcher at the same time.
  • The charms bar in this build appears to be blank.

Miscellaneous[edit | edit source]

  • The Administrative Templates section cannot be opened in the Group Policy Editor due to an error.
  • Opening the Windows Media Center may result in a SYSTEM_SERVICE_EXCEPTION bugcheck.
