Legal? Doubt it. Popular Game. Call the manufacturer or visit warez sites as suggested. It's not the same as say the posted info on changing the XP key. It is a FUNCTION of XP to do that one and nobody can be liable cept MS for FUCTIONALITY /tricks and tweaks. If you called MS they would have you do that with XP if you lost your WPA due to reinstallation. It's a handy tip too, write down that WPA that is legit and yer good to go afterwards with no phone calls needed.
