Changing your Windows XP Product Key

Its not very often I have to do this, but sometimes I do because I end up purchasing a bunch of matching machines, loading the software onto one, and ghosting to the rest.

So here’s a short guide on how to change your Windows XP serial number or product key.

Here’s the batch file I created to achieve the task. Simply create a new file called “changekey.bat”, and enter the following:

@echo off
echo Select “Yes I want to telephone a customer service representative to activate windows”,
echo click “Next”, then click “Change Product Key”, now enter your new key, then click “Update”.
@echo REGEDIT4 > %TEMP%\oobetimer.reg
@echo [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\WPAEvents] >> %TEMP%\oobetimer.reg
@echo “OOBETimer”=hex:ff,ff,ff,ff,ff,ff,ff >> %TEMP%\oobetimer.reg
@regedit /s %TEMP%\oobetimer.reg
@del %TEMP%\oobetimer.reg
%SYSTEMROOT%\system32\oobe\msoobe /a

That’s it!
