Change Windows XP Registered owner

Without doing a complete re-install, is there a way to "easily" change who the operating system is registered to?

Thank you.

 

Run the Registry Editor (REGEDIT.EXE).
Open HKEY_LOCAL_MACHINE\ SOFTWARE\ Microsoft\ Windows NT\ CurrentVersion.
To change the values of the RegisteredOrganization, RegisteredOwner, or ProductId, simply double-click on them.

Note: This will only change the registered user information for Windows, not for the applications on your system.
