Windows 8 build 7989

Windows 8 build 7989 is a Milestone 3 build of Windows 8, which was originally released on 18 June 2011 in the x64 architecture, then on 8 February 2020, an x86 checked/debug version of it was uploaded to BetaArchive.

Changes

 * The Windows Preinstallation Environment of this build is technically the first to use the Windows Basic theme.

Redpill
When the "Share" button from the charms bar is clicked, a file called shrscr.png is created in the %temp% folder, with a cat and 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 NDA that existed during Windows 8's development, implying that no images of the build can be shared.

Compatibility
To install or run this build in VMware Workstation, you must set the hardware compatibility to version 8.x or below; otherwise, a partially garbled system crash message will occur which will say "Your computer needs to restart. Please hold down the power button", such as error 0x0000001E or 0x0000000A. This error would occur right when the system kernel takes over the startup process but immediately crashes.

EFI
The x64 version of this build (2011 leak) appears to not support hardware with EFI, due to being bundled with an x86 7600 WinPE setup. To try and solve this, copy x64 7989's install.wim into an x64 7600/7601 WinPE setup, or deploy the image through DISM - this fix does not work for all UEFI configurations.

Start screen

 * When enabling Redpill, the start screen may appear to be empty.
 * There appears to be an option to "uninstall" the desktop on the start screen. However, selecting that option does nothing.

Aero Glass in Starter and Home Basic
This build automatically enables Aero Glass transparency even when installing the Starter or Home Basic SKUs, which is not supported by default. However, changing the color scheme (visual style) to another one and then back to the default one will disable Aero Glass.

Redpill
In this build's x64 compile (2011 leak) the twinui.dll file that is installed by default does not work with this build and will result in a broken system if redpilled. To fix this, run the following command in a command prompt and reboot before running Redlock:

Setup
At the end of setup, the message "Setup will continue after restarting your computer" can be displayed displaced.
