Windows 8 build 9200.16456 (win8 gdr soc intel)

Windows 8 build 9200.16456 (win8_gdr_soc_intel) is an internal post-RTM build of Windows 8. The contents of this build and its respective Recovery Environment image were first found on a prototype Intel Cloverview development kit, then later dumped and uploaded to the Chinese website BetaWorld on 25 July 2019. The dump was later shared by the aforementioned website on 17 November 2022, along with the Pan-European release of Windows 98 build 1577, Windows Vista build 6001.16637, and Windows 8.1 build 9468.

Findings
The build does not feature many differences over the official RTM build, apart from the inclusion of the Office 2013 suite, a preinstalled copy of CPU-Z (version 1.86.0 from August 2018), two versions of the Performance Trace Collection Tool from its  compile and build 8378, and respective drivers for the device it was intended to be installed on, which featured an Intel Atom Z2760 engineering sample. The build also includes various Internet Explorer favorited site links that point towards internal Microsoft, Intel and NVIDIA domains. Like other late partner builds compiled under the various  branches, it utilizes a test-signed certificate.

By default, this build's WIM dump includes several preinstalled security updates, overwriting part of the original build's binaries with variants intended for the public release of Windows 8. The binaries in question can be restored by uninstalling the aforementioned updates. Because the contents of this build were originally captured without LZX compression, the image size is approximately six times larger than the one from the RTM compile (12 GB compared to 2 GB).

It is worth noting that the device this build originated from was originally owned by former Microsoft executive Julie Larson-Green, who, at the time of this build's compilation, was promoted to head of the Windows engineering division on the same day; the device was later used by various Microsoft employees and automated accounts between 19 November 2012 and 11 January 2013. The associated account within the build lacks a password, although heightened password complexity requirements are enabled and will require the user to perform a password change on first log on.
