Windows 8 build 8375

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, whereas the ARMv7 compile was uploaded to BetaWorld on 4 July 2023, and subsequently shared by the aforementioned website on 26 October 2024.
Prior to its public upload, the Core SKU of this build was accidentally pictured in a set of screenshots for the third-party music player Gaana on the Windows Store. A forum thread referencing this build's x64 ISO image filename was posted on the Windows Live Connect forums on 14 May 2012,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 and several photographs of this build's ARM version running on a NVIDIA Tegra 3 Cardhu Reference Platform were also found on the BetaWorld Wiki.https://www.betaworld.cn/Windows_RT:6.2.8375.0.winmain_win8rc.120504-1900 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.
== ARMv7 compile installation ==
== New features and changes ==
* The Windows Fingerprinting Service has been partially re-enabled, compared to build 8370; in this build, it is in a half-way state where the confidentiality warning is displayed across all UI surfaces, but the actual fingerprint/EULA hash data is not displayed. Later builds from this release branch would disable this functionality entirely, only leaving behind a presence check for the WFS fingerprinting blob in the registry and within the OS installation's registry configuration directory (in Windows\System32\config).
* 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 displays the Windows wordmark, and would remain up through build 8509.
* The spacebar key can now be used to dismiss the lock screen.
* The Georgian Ministry of Education and Science Schools keyboard layout has been renamed to Georgian (MES).

=== x86 copy ===
As the x86 Enterprise copy of this build was dumped from an engineering sample device sourced from Lenovo, the provided image dump notably includes several development leftovers. These include calibration logs and debugging tools for the device's built-in GPS location sensor (from 5 May 2012 through 9 August 2012) as well as the needed drivers required for full functionality of the ThinkPad 2 such as chipset drivers for the Intel Atom Z2760 SoC, along with internal documentation sourced from Intel, Broadcom and Ericsson development teams.
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.
=== ARM32 copy ===
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. Tegra 3 HALs and Broadcom sensor and modem drivers from builds 8378 and 8381 are also respectively present in the image.
