Run Command - msoobe

Run Command - msoobe

Now that the Run application is open, type the following command exactly:

%systemroot%\system32\oobe\msoobe.exe /a

Now click the OK button.

Note: In the command above, the only space is between "exe" and "/a". Also, all of the o's are letters - there are no zeros in the command.

This command opens the Windows XP Activation Wizard where we'll change the XP product key.
