Seems like this should be easy, but I am not finding any information on how to remotely identify a Windows Server "core" installation as such, via WMI, Powershell or other method that can query lots of machines relatively quickly. I am trying to report on the percentage of servers we have running a core versus a full installation. Any ideas?
