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, which was shared on 7 May 2021 only in the ARM64 architecture. Prior to it being shared, the  file was shared to the BetaWiki Discord Server on 23 February 2020.

This build is notable for not containing any server components due to the lack of a .NET framework (which at the time of compilation was not supported for ARM64), in addition to it being the only build to include a Web Server SKU after it stopped being compiled regularly during Windows Server 2012's development. The available ISO 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.

While the ARM64 Server SKU uses Microsoft Confidential branding on, the Web Server Core SKU notably uses Windows Server 2012 branding.
