I am about to install windows 7 on my windows XP machine. The thing is that I have a mirror copy of my xp installation on another drive. I just want to make sure if I install windows 7 will it delete the key of my windows XP? If this is the case that installing windows 7 delete my XP key then what will be the way to revert back to my XP machine? Will my XP still be accessible & legal?
Thanks in advance.
