I guess I just dont know as much as I thought. I saw that the developers preview was out, and my friends told me it was awesome, and my step dad said it was cool too. So I installed it wanted to see how it felt. Anyways, I selected the copy files thing or whatever with it and it installed. Now I cant seem to uninstall it. I keep looking through the computer, but all I found was a window.old with all of my stuff in it. What can I do to get windows 7 ultimate back?
