Sometimes it becomes necessary to change the product key of Windows XP, but by default XP doesn’t provide any option to do that. As a result, many people may decide to re-install the operating system itself which is often a tedious and time consuming task .
However, here is a small hack using which it is possible to change the Windows XP product key without the need for re-installing it. This makes it possible to input a new product key and make your OS genuine. Here is a step-by-step procedure:
-
Open the Registry editor (Go to Start menu -> Run -> type regedit and hit Enter).
-
In the Registry editor navigate to:
HKEY_LOCAL_MACHINE\SOFTWARE\MICROSOFT\WINDOWS NT\CURRENT VERSION\WPA EVENTS
-
In the right-side panel open “OOBE Timer”
-
Edit/Change at least one entry there, press OK and close registry editor. This will temporarily deactivate your Windows.
-
In “Run” type the following command and press Enter:
%systemroot%\system32\oobe\msoobe /a
-
Activation wizard appears as follows:
-
Select the option “activation by phone” and click on “Next”. In the next page click on “CHANGE PRODUCT KEY” button, enter a new valid product key, press OK and close the wizard.
-
Reboot the computer. After the restart type the same command (as shown in step-5) in the “Run” box.
-
Activation wizard appears again and it shows the message WINDOWS IS ALREADY ACTIVATED.
That’s it! You have now successfully changed the product key of your Windows XP computer.
