Reinstall windows 7 from product key only
My copy of windows 7 has become messed up. Manually deleted a perental control software (son outgrew it) and messed up windows. I have run the system backup onto a CD and have backed up all files and data on an external HD. I've been told I need to reformat the C: partition and then do a restore. How do I reinstall windows 7 using the product key listed on the computer. No disks came with the computer. Win 7 was preinstalled by manufacturer.
