Is there a way to change a Windows XPs Serial number without reinstalling the whole thing?
This question could be coming from a person that is using a Microsoft known pirated version of Windows XP Professional Corporate Edition. Since I have no way of verifying any claims made to me via E-Mail, I ignore all “questionable” requests for such type of information. If you purchased a Legitimate copy of Windows, this should not occur and there would be no real reason to ever have to change your product ID or your serial number on a home system. Contact Microsoft Technical Support for assistance if you do have a valid reason to do such a task. The contact information is located in your manual that came with your particular version. If you are using a pirated copy of Windows XP, please do not ask me for help. I will not answer any questions with regards to pirated software.
