The OpenSSH client and server are now available as a supported Feature-on-Demand in Windows Server 2019 and Windows 10 1809! The Win32 port of OpenSSH was first included in the Windows 10 Fall Creators Update and Windows Server 1709 as a pre-release feature. In the Windows 10 1803 release, OpenSSH was released as a supported feature on-demand component, but there was not a supported release on Windows Server until now.
