This question has a comment from the OP, suggesting the fix
@Ramhound thank you, i finally sorted it . the "Windows Hypervisor Platform" needed to be unticked in the windows features... this i had done initially but what i didnt know is that "Virtual Machine Platform" needs to be unticked as well. Simple fix took me 2 days ! :-)
A new user then took that comment, and turned it into a (poorly formatted) answer.
Is this kind of behaviour promoted? Discouraged? Or does it really not matter?
