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. This build was leaked 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 was not supported for ARM64), in addition to it being the only build to include a Web Server SKU after it was removed during Windows Server 2012's development.
