Steps to re-activate Windows XP with different product key are:

Step 2: Now, registry editor window will open. Be careful at this point. Don't change anything or value unless you are told to do so.
Step 3: Go to the following location in your registry editor window:
HKEY_LOCAL_MACHINE\Software\Microsoft\WindowsNT\Current Version\WPAEvents
Below is one sample screenshot:

To confirm whether your XP window is deactivated or not, type following command in Run.
%systemroot%\system32\oobe\msoobe.exe /a
