   Continue to expand folders until you reach the HKEY_LOCAL_MACHINE\Software\Microsoft\WindowsNT\Current Version\WPAEvents registry key.

   Click on the WPAEvents folder.
6. 
   In the results that appear in the window on the right, locate OOBETimer.
7. 
   Right-click on the OOBETimer entry and choose Modifyfrom the resulting menu.
8. 
   Change at least one digit in the Value data text box and click OK. This will deactivate Windows XP.
   Feel free to close Registry Editor at this point.

   Click on Start and then Run.
10. 
    In the text box in the Run window, type the following command and click OK.

12. 
    Click the Change Product Key button at the bottom of the window.
    Don't worry about filling anything out on this screen.
13. 
    Type your new, valid Windows XP product key in the New key:text boxes and then click the Update button.
14. 
    You should now reactivate Windows XP by following the instructions on the Activate Windows by phone window which you should now be seeing or via the internet by clicking the Back button and following the instructions on that screen.
    If you'd rather postpone activating Windows XP until a later date, you can click the Remind me later button.
15. 
    After activating Windows XP, you can verify that activation was successful by repeating steps 9 and 10 above.
    The Windows Product Activation window that appears should say "Windows is already activated. Click OK to exit."

Use the Activation Wizard If you have only a few volume licensing product keys to change, you can use the Activation Wizard. Warning! This document contains instructions for editing the registry. If you make any error while editing the registry, you can potentially cause Windows to fail or be unable to boot, requiring you to reinstall Windows. Edit the registry at your own risk. Always back up the registry before making any changes. If you do not feel comfortable editing the registry, do not attempt these instructions. Instead, seek the help of a trained computer specialist. Note: Microsoft recommends that you run System Restore to create a new restore point before you complete the following steps: Click Start, and then click Run. In the Open box, type Regedit, and then click OK. In the left pane, locate and then click the following registry key: HKEY_LOCAL_MACHINE\Software\Microsoft\WindowsNT\Current Version\WPAEvents In the right pane, right-click OOBETimer, and then click Modify. Change at least one digit of this value to deactivate Windows. Click Start, and then click Run. In the Open box, type the following command, and then click OK. %systemroot%\system32\oobe\msoobe.exe /a Click Yes, I want to telephone a customer service representative to activate Windows, and then click Next. Click Change Product key. Type the new product key in the New key boxes, and then click Update. If you are returned to the previous window, click Remind me later, and then restart the computer. Repeat steps 6 and 7 to verify that Windows is activated. You receive the following message:Windows is already activated. Click OK to exit. Click OK. Install SP1 for Windows XP. If you cannot restart Windows after you install SP1, press F8 when you restart the computer, select Last Known Good Configuration, and then repeat this procedure.

If you wish to use your key, you should be able to find that option in the Start menu. Click Start, and go to accessories. Inside that folder, select System Tools. Now you should see an option to activate Windows. Click that, and follow that prompts. When you are done, you may need to restart your computer to apply the license. Note that, if you used a banned key which resulted in Windows being "non-genuine," then you may just need to reinstall the OS.
