I just wanted to write a small blurb regarding the PowerShell cmdlet Add-WindowsFeature. If you are using Server 2012, it is now called Install-WindowsFeature. Here’s a write-up about it:
The Add-WindowsFeature cmdlet has been replaced, starting with Windows Server 2012, by the Install-WindowsFeature cmdlet. For more information about Install-WindowsFeature in Windows Server 2012, see Install-WindowsFeature. For more information about Install-WindowsFeature in Windows Server 2012 R2, see Install-WindowsFeature.
NOTE: If you are trying to run Add-WindowsFeature on a Server 2008 R2 box and the cmdlet is not recognized, it is because you first need to install the server manager module. Run the following to do so: Import-Module ServerManager
