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.

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, code integrity component ( CI.DLL), and some 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.
