Question

what kind of ‘unique’ system identifiers can be easily obtained using C# (to hash and then uniquely identify a system)? I could just hash HDD size and things like that but I need to identify and distinguish computers that are all built by the same components so I can’t go by that.

Appreciate hints, ideas, sample code!

Answer 1

Here’s a good start with WMI …

// Win32_CPU will work too
var search = new ManagementObjectSearcher( "SELECT * FROM Win32_baseboard" );
var mobos = search.Get();

foreach (var m in mobos)
{
  var serial = m["SerialNumber"]; // ProcessorID if you use Win32_CPU
}

You can do that with many pieces of hardware and come up with a solution.
