I need to reinstall windows because of a few errors that need to be fixed (easiest way to fix them IMO). I have BF3 and MW3 on my PC at the moment. Obviously I want them after my reinstall. Is it as easy as putting the disk back in and installing it like I did the day I got it? Or will it say the key has already been used? Do I have to back up my games? I would really appreciate help.
Thanks in advance,
