Found this blog quite helpful in the middle of a deployment, when getting “Failed to open the runspace pool. The Server Manager WinRM plug-in might be corrupted or missing” in GUI.

Install-WindowsFeature DHCP -IncludeManagementTools
Get-WindowsFeature
Install-WindowsFeature WINS -IncludeManagementTools
Get-WindowsFeature
