Windows 8 build 7875 is an interim build of Windows 8. Eight screenshots of this build were included with the original upload of build 7746 on 3 May 2020 and the build itself was eventually shared on the BetaWiki Discord server on 31 December 2020.

New features and changes[edit | edit source]

This build already showcases significant evolution from 7850. File search was implemented along with application search, and the kernel version was changed to 6.2. This build also changes the first letter of search suggestions to blue.

Microsoft Confidential has been added into the winver banner, replacing the original version from Windows 7 and the desktop watermark now says "Microsoft Pre-release Windows Operating System". Additionally, the copyright date on winver.exe has been updated from 2009 to 2010.

This build also contains the first iteration of the new login screen, which looks identical to Windows 7 but with the aforementioned operating system's logo removed. Enabling Redpill changes the design of the user selection to a larger version and uses the wallpaper from a logged in user as a background.

Aero is also updated, with a smaller caption button in some dialogues.

Setup[edit | edit source]

Setup is mostly similar to the previous leaked build of Windows 8 albeit with the watermark showing on the bottom-right corner. The Windows branding in the OOBE has been swapped out with a disclaimer stating that the build in question is confidential Microsoft material.

Bugs[edit | edit source]

Installation[edit | edit source]

  • The messages shown when the Setup is starting or restarting the computer are cut off.
  • When booting in to OOBE after an upgrade, the system might bugcheck with the code SYSTEM_SERVICE_EXCEPTION.

Arial[edit | edit source]

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

Aero[edit | edit source]

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.

Desktop Window Manager[edit | edit source]

The Windows Basic and the High Contrast themes do not properly render due to the enforcement of the DWM Aero theme.

Drivers[edit | edit source]

Upon using drivers released somewhat after the compilation of this build, a BSOD will appear after installing the drivers. The error code for this blue screen is 0x000000FC.
