Changing Windows XP SP3 Product key

[Mike UK]

Anyone know of any programs to change the product key?

I have tried Microsofts own but it fails due to an unknown error (Possibly because Windows is already registered with a legal product key?)

Cheers

Just out of curiosity, why do you want to change it if it has a legit one on it?

Just phone the number to activate by telephone, option 1 at the end and get your new code...

I think you just need to run the XP activation again and there should be a change product key option somewhere (under telephone a representative maybe?)

I think you need to run c:\windows\system32\oobe\msoobe.exe /a

EDIT: infact here seems you just need to alter a registry value so you can run the activation wizard again

10 Identical computers to set up and each has a different COA

I set up and imaged one so I would only need to fully set up one machine.

Also thanks to Microsofts site this worked to de-activate and re activate using a different key

Thanks for the advice.
