I am trying to setup a few VMs on my Windows 8.1 Pro 64bit desktop computer. I have successfully installed the Hyper-V windows feature but when I actually try to create a VM, after clicking the "Finish" button I get an error message (see image below) and then Windows informs me that it will restart in 1 minute (see second image below). For that 1 minute I can't really do anything - a lot of windows functionality becomes disabled. And then it restarts just like it said it would.
Originally I was getting this error from my installation that had been upgraded twice - once from Windows 7 Pro to Windows 8 Pro and then recently to 8.1 Pro. Reading around I discovered several people with the same problem after upgrading to 8.1 and a reinstallation fixed it. So that's what I did - I did a clean Windows 8.1 install (not 8 and then upgrade to 8.1) and then the first thing I did was enable Hyper-V and test it. Voila! It worked! Then I continued setting up my computer (which includes connecting it to our server 2012 essentials domain) and now I'm back where I started. It seems that connecting myself to our domain may have been what broke it.
I have also tried logging into my local admin account (the same one that I originally used after reinstallation) but it also does the exact same thing.
Any ideas what I can do to fix this?
