MAC-address of the Network card is one of the widly used identifiers...
As long as you realize that a determined person can circumvent it... Some combination of hostname, MAC address, other system stats. You could get the machine GUID directly from Windows, but again, this can be faked. Just type GUID into an MSDN search.Quote:

And lose customers whenever they upgrade the bit you're dependent on?
Unless you pull an ID from several different sources, and tolerate a certain amount of change from the baseline.
