Anyone know where the hardware key for the Linksys WMCE54AG is stored in a MCE2005 machine's registry. You have to enter a key that comes with the setup disk in order to validate the extender when installed. I still have the disk. I have registered with both Linksys and Microsoft, but have misplaced the flimsy envelope on which the key was printed. If I can't find the key I would like to grab it from the registry of the MCE machine. Does anyone know where this is located in the registry?
