Unique value for PC?

[OwenWatson]

I'm wondering whether there's any value on a PC that is reasonably unique to that PC. I had a look at the mac address but that's a bit difficult to extract. A registry value that could be expected in all PCs W2K+ and sorta unique would be good.

Not high security, just some security. . .

RegRead("HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorer\Registration","ProductID")

Will return the Product ID of windows which in THEORY should be fairly unique.

use the MAC address - Windows might get pirated, or you might have a site license or something like that, but who clones NICs?
