If you type systeminfo at the command prompt, there is a listing for Product ID. Can someone explain what this is exactly, and would it make a good seed for a registration code algorithm?
A:
It's a good start. But (IMHO) you can use directly a GUID. Read more here: http://en.wikipedia.org/wiki/Device_fingerprint (read about Active fingerprinting)

A:
i believe it's representative (or is) your windows product key. Either way, all you really want is a GUID.

You can find the product ID of your installation by right clicking on My Computer and choose Properties, then viewing the General tab. You can also find the product key in the registry at: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\ CurrentVersion\ProductId.
