Windows 8 build 7899

Windows 8 build 7899 is a build of Windows 8. Two screenshots of this build were included with the original upload of build 7746 on 3 May 2020, and the build itself was eventually shared online on 19 July 2020. Unlike build 7880, the text on the boot screen is condensed.

Redpill
Many changes have occurred since build 7880. Accents and backgrounds have been implemented, accessible using a registry key. The Start screen now has multiple views - while this is hinted at in 7880 by the existence of a "Move to Other View" option found while right-clicking on the Start screen tiles, it is unimplemented. This other view is an "Other Programs" view containing all installed programs. As a result of this, there are far less applications in the default Start screen view. Animations have been implemented. Tile colors have been changed to be more uniform.

A user tile is now located at the top of the screen filled with the user's profile picture (replacing the Search button, which was not seen again on the Start screen until Windows 8.1 Update 1 in 2014), as well as a volume icon. To replace the Metro Horizon (removed, although not entirely so, in build 7878), a Desktop tile has been introduced. Clicking it brings the user back to the classic Windows desktop.

There have also been an immense amount of changes outside of the Start screen. An ImmersiveSettings app has been introduced, the ancestor of PC Settings, and several apps have been redesigned to fully use WinRT. Auto Colorization is no longer enabled by default on the Aero theme. ImmersiveBrowser, or IE Metro mode, has also been implemented. Advanced Task Manager, a more advanced version of Task Manager, has been implemented as well. The Metro OOBE also had a major overhaul. The login screen was updated and pattern login now works. The Metro downspace has been dropped in favor of the snap function.

The blue screen of death has been redesigned in this build, dropping the design seen in Windows XP in favor of a simplified black screen informing the user that their computer requires a restart, along with the bugcode (minus the parameters). This bugcheck screen utilizes the Segoe UI font, leveraging the VBE functionality that was implemented in earlier builds and the BGFX subsystem. However, in the event that the system crashes early in boot before BGFX is initialized, a fallback is used which merely dumps the bugcode parameters along with a short message prompting the user to hold down the power button.

Start screen accent
To get the Start screen accent, open Registry Editor, head to, create a new key called DWM, make a DWORD called EnableAccent and set its value to 1. Afterwards, log off and then log back on again.

As this build's implementation of the accent is incomplete, visual artifacts may appear across the screen.

Removable media prompt
The removable media prompt has been revamped as well, using the new Metro design. It mostly consists of the same actions as the previous removable media prompt used in earlier builds of Windows 7.

UEFI class 3

Arial
This build uses the Arial font for the title bar and watermark because of a typo in the  and   files.

When booting into safe mode, Explorer may crash after logging in.

Login sound
Upon logging in, the login sound will play three times instead of once.

Aero Glass on the Home Basic SKU
The Home Basic SKU doesn't support Aero Glass borders by default, but it can be enabled, like in build 7880, by clicking on "Windows 7 Standard" color scheme in Window Color and Appearance dialog from the Display control panel item.

Upgrading
To start the upgrade process, you must use  in the sources folder, or else setup will say that a problem occurred.
