Change your XP CD Key

There are a lot of people out there who haven't upgraded to service pack 2 because they installed XP with a pirated CD key. This puts your system at risk since SP2 contains many security updates. But you may be wondering if you'll have to reinstall XP if you do come clean and purchase a license. The good news is that you don't have to reinstall - You can edit the registry to change your product key, or you can forego that hassle and use a handy little utility to change the CD key recorded in Windows to the new, legit key on your license (which will then be recognized as legal by the Windows Genuine Advantage program).
