Does anyone know of any program that allows me to change my product key from volume license to OEM? I lost my recovery cd's and have used a disk that had corporate licensing. I tried to change the key using the activation utility that is pre-installed on XP, but to no avail. The keys are obviously different during the installation of XP, so I had to use the volume license key to install it and get the updates. Any help would be appreciated. Thanks guys.
