Hi all, I am trying to find a solution to these questions. I have a HP laptop with Windows 7 Home Premium and I would like to do a fresh install of Windows 7. I download the Win7 image from Digital River. My question is can I install Win7 Ultimate? If Yes or No, how do I install and activate Windows? I read that there is something in the c:\windows\system32\oem that I need??? How is that come into play? Can you give me step by step list or point me in the right direction? Thanks.
