Just installed Parallels 11 and then upgraded from Win7 to Win 10. It seems to go normally. Tried to restart windows and go the "administrator welcome" screen. Clicked on "sign in". The image magnified, a few moments of the balls going around in a circle, and then the screen goes black. It goes no further. I can bring up the task manager but that is about it. It never makes it to a home or start screen.
Help?
