So I bought a computer from my friend. It originally came with Vista x64 on it and he had upgraded to 7 x32, but I wanted to upgrade again to 7 x64 because half of the 8gb of ram was going to waste on x32. The computer didn't come with the serial or the Windows discs, so I wrote down my product ID, formatted my hard drive, formatted the NTFS partition, and installed Win 7 x64 on the formatted drive with a fake DVD (planning to enter my genuine serial into it of course). Then I realize that a product ID (which is all I wrote down) and a product key are NOT the same thing. If I had just used a third party prog to pull the KEY and not the ID before formatting the drive, I wouldn't have a problem, but now I think I'm f*cked. I'm currently unformatting the NTFS partition now to see if I can find the Windows 7 x32 key in the remains, bit I am NOT optimistic. Anyone have any amazing ideas so I don't have to crack my legally owned Windows? I was thinking about calling Microsoft, but I don't know if they'd issue me a serial number with just a product ID and no disc...
