This tutorial explains how to change your windows xp product key / xp serial / xp license without using software or reinstalling. To do this you need to edit the registry to deactivate windows, then run msoobe.exe to enter your new product key.
1. Run regedit and drill down to:
HKey_Local_Machine\Software\Microsoft\WindowsNT\Current Version\WPAEvents.
Select WPAEvents then on the right double click “OOBETimer” and change at least one digit of this value to deactivate windows.
2. Choose run from start menu and type this command in the run box:
%systemroot%\system32\oobe\msoobe.exe /a to get the Activate Windows wizard, select “Yes, I want to telephone a customer service representative to activate Windows”, click next.
3. In the next screen click the “Change Product Key” button.
4. Now enter your new product key, then click the update button. Close the wizard and reboot.
5. When your computer restarts, enter the command in step 2 to verify windows is activated and you should see “windows is already activated”.
Changing your xp key is perfectly legal despite what many think. You can even automate the process with a visual basic script which you can find on Microsoft’s website.

Hi Dani, you need your own product key. If you are using the key in the image it won’t work.
