Windows Server 2016 vs. 2012R2 PowerShell

Whilst setting up a new server for Skype for Business (I know it’s not supported but want to test it out), the usual Add-WindowsFeature in PowerShell does not work with Server 2016.  You have to use the Install-WindowsFeature instead to add in all the pre-reqs that you need.

The other thing I noticed is that being logged in as a user with Domain Admin rights wouldn’t work, I had to be logged in with the Domain Admins account to use the Install-WindowsFeature (even when running an elevated prompt).
