I have a situation where I am deploying a number of identical PC-based systems that have the new Windows XP Professional for embedded systems COA. I want to create a standard disk image and rattle that off to multiple flash drives in a production environment. The problem is that the windows serial number will be the same on each image. The Windows key update tool apparently requires a live internet connection, which I don't have available on the appliance I am building. Supposedly this version of Windows does not require activation. Why do I have to have an internet connection to change the serial number? If I change the serial number, is it going to try activating itself and totally hose the installation? Is there some other way to change the serial number without messing up the registry?
