Windows Server 2016 build 10586 (th2 srv1 nano dev2)

Windows Server 2016 build 10586 (th2_srv1_nano_dev2) is a build of Windows Server 2016, the ARM64 compile of which was uploaded on 7 May 2021. This build is notable for not containing any server components as they were not built into the included editions. It is also one of the few builds to be available in the Web Server SKU after it was discontinued during the development of Windows Server 2012 and only kept around internally as the base edition for other SKUs. Unlike the other supported SKUs, the Web Server SKU uses Windows Server 2012 branding as opposed to a simple Microsoft Confidential banner in.

The available copy of this build is unstaged and contains private symbols for the kernel, the code integrity component, and a number of drivers. The kernel uses a debug build of PatchGuard; although obfuscation of PatchGuard code is still in place, there is a debug string mentioning that PatchGuard is in "evaluation mode" and to "contact kejohns" on a PatchGuard false positive. Unlike other Server 2016 builds, this build uses test signing and as a result can be installed on the current date.
