Windows Subsystem Linux (Ubuntu on Windows)
Would be great have Bash on Windows Server like Windows 10 have. Some tools will be useful like ssh to connect others remote linux servers. Apache, php, mysql ... There are so many reasons to improve that tool. Admins can otherwise activate or not.
WSL is on the latest Server builds and the OpenSSH beta is in full swing. Key word is beta.
OpenSSH (Client and Server) is already there, provided by Microsoft: https://github.com/PowerShell/Win32-OpenSSH/releases
