'''Windows 8 build 8375''' is the official Developer Preview 7 build of Windows 8, released to partners enrolled into the Ecosystem Engineering Access Program on 5 May 2012. The available copy of this build's x86 Enterprise SKU was dumped from a Lenovo ThinkPad Tablet 2 engineering sample and was uploaded on 25 January 2021, while as the ARM32 compile was uploaded to BetaWorld on 4 July 2023, then later shared by the aforementioned site on 26 October 2024, prior to which, various images of said compile were found on said site.

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,<ref> https://social.microsoft.com/Forums/en-US/dd6dd009-fde2-4aa6-b235-8725060163bc/live-sdk-50-can-not-used-on-windows8-rc-8375-version?forum=messengerconnect</ref> and several photographs of this build's ARM version running on a NVIDIA Tegra development kit were also found on the BetaWorld Wiki.<ref>https://www.betaworld.cn/Windows_RT:6.2.8375.0.winmain_win8rc.120504-1900 </ref> In addition, various binaries related to the ARM32 compile, particularly the Windows Store General Helper Tool used to debug AppX application installation, were found within a disk dump for Windows 8.1 build 9354 (winmain).

Similar to the unidentified December 2011 build, build 8509 and build 9200.16456 (win8_gdr_soc_intel), despite not being publicly released by Microsoft, the standard set of built-in Metro applications is included by default.

* This is the first available build to use the new default wallpaper seen in the official Release Preview build (originally titled Shorty), albeit with a 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 up through build 8509.

The Windows Hardware Certification Kit from build 8523 is additionally present in the provided image, and scripts for updating the firmware included as part of hardware components found within the development kit are present in a separate user account named 8375RC. The image is set up to use a key management server from Microsoft's internal corporate network that was made available to partners.

The ARM32 copy of this build includes a private compile of Internet Explorer 10, version 6.2.8375.0 (winmain_win8rc(darrenda).120517-1502), as well as the Application Certification Kit and Visual Studio remote debugger toolsets targeting OS builds 8378 and 8371, respectively.
