Windows 8 build 7989 is a Milestone 3 build of Windows 8, which was originally shared on 18 June 2011 in the x64 architecture as a capture from an installation on a HP notebook,[1] then on 8 February 2020, an x86 checked/debug version of it was uploaded to BetaArchive. The unmodified version of the x64 architecture's ISO image was later found on 18 June 2022. Prior to its publication, various pictures of this build were posted to the My Digital Life forums on or before 17 June 2011.[2]

Unlike the earlier compile of build 7985, the "Welcome" text on the boot screen is still as small as in the fbl_core1_kernel_npc compile of build 7973.

Redpill[edit | edit source]

When the "Share" button from the charms bar is clicked, a cat image called shrscr.png is created in the %temp% folder, with text saying "U can haz no pix. GIMME FISH" along with a bug ID at the bottom. The text is most likely a reference to the strict Non-Disclosure Agreement (NDA) that existed during Windows 8's development, implying that no images of the operating system can be shared.

Bugs and quirks[edit | edit source]

Compatibility[edit | edit source]

To install or run this build in VMware Workstation, the hardware compatibility version must be set to versions 8.x/9.x; otherwise, a bugcheck will occur.

EFI support[edit | edit source]

The originally leaked x64 version of this build from 2011 does not support EFI hardware as it was bundled with a boot.wim image from the x86 version of the Windows 7 RTM build. To resolve this, either copy install.wim into an x64 installation disc of build 7600 or 7601, deploy the image through DISM, or copy the installation files from the x86 version of the Windows 7 RTM build using the x86 version of Windows 8, Windows 8.1, or Windows 10 installation disc.

Start screen[edit | edit source]

  • When enabling Redpill, the start screen may appear to be empty.
  • Like build 7985, an option to "uninstall" the desktop from the Start screen is present but does not function.

App tiles[edit | edit source]

Some app names (such as Control Panel, Chess Titans, Defragment and Optimize Drives, etc) may be truncated by normal sized tiles.

General[edit | edit source]

If using VMware Workstation versions 15.x or above changes in build 7878, attempting to restart or shutdown in this build will cause a softlock. To fix this, use the Power menu from the VM section. This bug persists until build 8008.

Aero Glass in Starter and Home Basic[edit | edit source]

This build automatically enables Aero Glass transparency after installing the Starter and Home Basic SKUs, despite product policies limiting usage of such effects. Changing the current visual style over to a different one (e.g.: Windows Basic) will disable glass effects.

Redpill[edit | edit source]

The original x64 leak from 2011 has a malformed twinui.dll binary that is installed by default, which will result in the user interface failing to initialize properly if redpilled. To fix this, run the following command under a command prompt and reboot before running Redlock:

sfc /SCANFILE=C:\Windows\System32\TWINUI.DLL

Keyboard layout switcher[edit | edit source]

The systray element for the keyboard layout switcher appears dithered.

Bug when disabling DWM[edit | edit source]

If you had an application and Metro search bar (or anything other than it) before disabling DWM, you may see the application as a black background and the search bar may appear again. To fix this, enable DWM again and restart to see it working with DWM disabled.
