Hyper-V could not initialize (rights?)

Question

Hello,
I have an WIN2012 R2 Server.
Unfortunatley it is serving as a DC (I know this is not recommended).
I set up the HYPER-V role and when I start I receive with a newly created VM (no etwork connected yet):
'TEST111' could not initialize. (Virtual machine ID 49608249-F381-43E8-BCCF-F6C61CDE68A0)
Event ID 3040
Most likely it has something to do with the rights. I tried to apply this thread, but no luck:

I reinstalled the role and it still does not work. It looks like the old Settings of the hyper-v program stay on the machine after deinstalling the role, because after the reboots and Setting it up again it Shows the old Settings.
The process Monitor Shows:
HKCR\Applications\vmconnect.exe : NAME NOT FOUND Desired Access: Read.
Q:
Is there a way to completly clean the hyper-v stuff?
It might be that hyper-v only accepts local admin users (especially on a DC)?

Hi,
The not recommend setting up often cause complex issue and hardly to locate the problem point when you troubleshooting, I don’t have the same environment but after you install
the Hyper-V role, the Hyper-V Administrators local group will created automatically, Please confirm your current user is the member of the Hyper-V administrators group user.
Hope this helps.
