Does your windows 10 Pro install contain all 19 User Groups or just 11
I have two installs of win10 Pro. One was a clean install and one was upgraded to Pro from Home in a VM. I found I could not add Remote Desktop users to my upgraded version because groups were missing.
So take a look under Computer Management --> System Tools -->Local users and Groups --> Groups and report what you find
Which does it look like? I have one of each
