Pre -> Already Done.
It Means You Don't Need To Crack It.
Buy the games! :D
eaiser to download programs that are already cracked so you don't have to go looking for a crack or pass key..
if your trying to say that you have windows xp registration key and have downloaded a trial of windows 7 or even a torrent and it bugs you to ask for a key then no it is not possible however you can buy license keys which round off to the same price as the installation disk which includes more features... As torrent downloads on the other hand you can download precracked or cracks which will skip the registration part...
