Update Your Product Key: Select Your Version of Windows
In 2003, TechRepublic first published the procedure for changing the Product Key in Microsoft Windows XP. Since then, Microsoft has made the process easier and safer by providing an applet for just that purpose. Mark Kaelin shows you the applet and the new process.
The first step is to go to the Genuine Microsoft Software self-help page, Update Your Product Key: Select Your Version of Windows.
The procedure outlined in this Photo Gallery is also available as a PDF in a TechRepublic Download and as an entry in the TechRepublic Microsoft Windows Blog.
This gallery was originally published in July 2009.
