So I was temporarily using Win7 Ultimate that was a not so registered version for several months and have a lot of programs on the HD. I just recently got a Win 7 pro installation disk and Key. Is there any good way to re-install/switch to the Win7 pro without formatting or deleting the programs and data I already have on my drive?
I followed the directions and performed an "upgrade" When I try to enter the Key it tells me that this key is not not the correct key for this version of Windows 7. But this is a win 7 pro key. Are there any issues with upgrades reading the key wrong vs a clean install?
