Windows 8 build 8375

Windows 8 build 8375 is a build of Windows 8, which was shared on the BetaWiki Discord server on 25 January 2021 as a complete drive dump in the WIM format, originating from a prototype Lenovo ThinkPad Tablet 2 (codenamed Coltrane). Prior to its public upload, the build was accidentally pictured in a set of screenshots for the app Gaana on the Windows Store. This build shows the Microsoft Confidential watermark but it does not show the build hash at the end of the tag.

This is the first available build to use the new wallpaper that was used in the official Release Preview build, albeit with slightly higher color temperature and saturation. The boot screen was changed from the betta fish that was used in the official Consumer Preview build to a plain black screen that simply contains the word "Windows®". This boot screen was used until build 8441.

Despite being an internal build, Metro apps are included by default.

Several screenshots of an ARM version of this build were shown on the Chinese website BetaWorld.
