Re: Power off problem
Not seen this problem myself but do know that if the iso is burnt too fast then sometimes problems can appear. I'm not saying this is what you've done but perhaps just worth mentioning. Also problems can appear if the download wasn't a clean one. This happened to me with the consumer version and I ended up re-downloading the iso.
One other thing that might help you.. If you place the mouse cursor in the top right corner to bring up the 'Charms', click on settings, then more settings and then 'General'. You'll then see on the right a way to refresh the installation. Please do post back if this doesn't help your problem.
