I'm pretty sure there's some kind of unique ID for everybody's system. Some
kind of Security System ID SSID or something along those lines. I've seen
these before and wondered if anybody knew how to retrieve one of these for
the system. Or if there was some other unique information I could find on a
system?

There is a Windows Product ID that you can see by right-clicking on "My
Computer" and clicking on "Properties". It is under "Registered To" on
the "General Tab". This Windows Product ID is unique to each computer
and can be found in the registry under
HKEY_LOCAL_MACHINE/SOFTWARE/Microsoft/Windows/CurrentVersion/ProductId.
You can use the Microsoft.Win32.Registry class to access the registry
and get this value.
 
So this is in no way tied to the Windows Product code entered when
installing? I'm just wondering what this is based on so if our software is
used at a place that has the same product code of windows on multiple
machines. Albeit this is illegal, but just need to know if this is truely
unique.

You could search Microsoft for "product activation". For example, there's a
WMI provider (and maybe direct APIs) that return the unique activation hash
that things like XP use. That's machine-specific.
