Powershell – Server 2012 Server Core powershell not installed

powershellwindows-server-2012

In server core, after a restart powershell was all of a sudden not installed, what do I do to reinstall it?

I do not have remote administration set up yet so I cannot use that to re-install it.

'powershell' is not recognized as an internal or external command, operable program, or batch file.

Use the Deployment Image Servicing and Management (DISM.exe) tool to enable PowerShell:

dism.exe /online /enable-feature /featurename:MicrosoftWindowsPowerShellRoot

...or if that's not enough:

dism.exe /online /enable-feature /featurename:MicrosoftWindowsPowerShell /all
