Hi guys,

I've just upgraded to windows 8 beta 64 bit about 3-4 weeks ago and it worked quite well at the very beginning. But now the only thing i wnat to do is to uninstall it because my pc is running more and more slowly. and of course there are so many other problems.

After long consideration, i plan to install windows 8 and back to win 7 Uti. But uninstall windows 8 with no success.

does anyone know what could be causing this? many thanks in advance.
