Boy oh boy, this is something I have been looking into for a while. Firstly you can use the mac address, then I got a link to something that allows cloning or changing your MAC address. Then there is the registry. There are certain things I can look for and have in the past but it can be changed and may not be secure. What I am looking at now is the "Hardware\\Description\\System" area of the regitry. This area in the registry is updated everytime you reboot your PC. Changing it may be possible, but a reboot will revert it to it's ORIGINAL state / values. Not sure how to read it though, it is a MultiString(??)
