I don't think that this value is different on each PC.
I would try to get several values - hard disk serial number, MAC address, user SID, computer name, various hardware parts ids, location (from IP). If 1-2 of them changed, it still is the same PS. If all changed, it is another PC.
Or generate a GUID and, store it in registry, and use it as a private unique id of that computer.
