Retrieve volume serial number (or some other unique ID)?

[ratty]

Is there a way to grieve the VSN or some other unique HDD ID without Advanced Volume Object?

There is a number of ways to generate a unique ID other than the Hard Drive serial.

If you're looking for something unique such as 'machine installation' for your game/app, you could do something as simple as get OSVersion/OSBuild/Username/Computer Name, hash it all together and generate a unique string.

If you're looking for something much more advanced, you could look for other hardware IDs. CPU ID's are very rare nowadays, intel stripped it out but there are other HardwareIDs.

A good fail-safe is to use the Machine GUID located in the registry here: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Cryptography

Username can lock out other users on the machine, id think.

Does the MachineGuid require any special permissions to read? That seems to hang up some of the basic Windows user accounts.

I can't even get MMF to read the MachineGuid. Any chance I could ask you to make a quick example? I'd put it to good use
