HELP! CD-Key changer for warcraft 3

[Swifty666]

Please help me i bought warcraft 3 for playing on a network and installed it all with origional CD-Key. Says i can't play because of the same CD-Key is used. I phoned up and purchased enough CD-keys but dnt wanna have to uninstall and re-install them all. How do i change them without doing so?! :doh:
Thanks in advance

You have to go to Run type in regedit and then find warcraft 3 and then you will see the CD key and then just edit it.
