This comes up from time to time, but the problem is how to RELIABLY obtain information from the system. I began by using the Windows API to get the disk volume id, but I found this fails to report on some systems. I suggest it is better to use MS's more recent Windows Scripting class to get this reliably.

For example ...
oFSO = CreateObject("Scripting.FileSystemObject")
nVolumeSerial = oFSO.GetDrive("C:\").SerialNumber

SCRRUN.DLL must be present in the WinSys folder (it is on ME and Win2K, and you can update older versions of Windows with a download from MS). SerialNumber is a long integer. You can convert this to hex to get the familiar ABCD-0123 volume id string. Then encrypt to use as a licence key.

To be really fancy, you might identify other hardware items. A thread a little while back had methods for doing this with the network card.
