Yep, that is where I downloaded my thumbdrive installs. The first upgrade went without a hitch and I used it for several hours, when I updated the icon sizes on the task bar it asked me to log off, so I shut down and rebootet on reboot it would look like it was loading normally and then end up with a desktop image with the network taskbar icon, but no desktop icons and no mouse pointer.
I eneded up using F8 to get the built in recovery console, but alas I did not yet have any restore points. I tried the fixboot option and it couln't complete that either I tried just about everything and as a last resort tried the roll back to last build, which hung up too, but a hard reset got it going and I am back to win 7 for now.
I may either retry on this computer later on or try a clean install if the retry doesn't work. In the mean time I'll practice on a few back computers.
