Windows 8 build 8375 is a Release Preview escrow build of Windows 8. The available copy of this build was dumped from a prototype Lenovo ThinkPad Tablet 2 and was uploaded on 25 January 2021.

Prior to its public upload, the Core SKU of this 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 does not show the build hash at the end of the tag. A forum thread referencing this build's x64 ISO image filename was posted on the Windows Live Connect forums on 14 May 2012,^[1] and several photographs of this build's ARM version running on a NVIDIA Tegra development board were also found on the BetaWorld Wiki.^[2]

Changes[edit | edit source]

This is the first available build to use the new wallpaper seen in the official Release Preview build, albeit with slightly higher color temperature and saturation. The boot screen was changed from the betta fish used in the Consumer Preview to a plain black screen that simply contains the word "Windows®", and would remain until build 8509.

Similarly to the unidentified December 2011 build, despite not being publicly released by Microsoft, the standard set of built-in Metro applications is included by default.
