have you,4 CoD, installed win7 over XP?

You seem to have made all the preparations you need by backing up your data and downloading new drivers.

Nothing really to add to that. I moved to Win 7 64-bit from XP last year and it all went very smoothly. Windows 7 is fairly good at installing drivers automatically, but you will have to manually add a few bits and pieces I'm sure once you have the basics in place.

Good luck.
