will I be able to use my upgrade serial number
I have preordered a copy of W7 Home Premium and expect to recieve on 10/22. I have installed a copy of W7 Home Premium RTM in a clean install after removing Vista Ultimate. Will I be able to upgrade the RTM copy on my computer by just entering the serial number and then activate it or will I have to do another clean install and use my Vista disk to prove upgrade?
