This morning I upgraded to Windows 10. The installation appeared to go smoothly, and Windows 10 was running on my VM. I followed the final instruction on Parallels' walkthrough, and changed the name of the VM from Windows 7 to Windows 10. I don't know if this was the cause, or a coincidence, but now I cannot shut down Windows 10. It appears to be Suspended, but when I try to Resume, I just get a black screen. In the Parallels General Settings I have this: Can anyone offer a suggestion? It looks like I need to Shut Down, but when I attempt to do that, it only Suspends Windows, and I'm not even sure it's doing that correct.y And at this point, I can't even undo the last simple change to the VM name.
