So, that is why I wanted to verify manually in Windows to see which one would be mostly the good one. The thread is in the .NET forum, if you wish to take a look at it.

I was the thread. Is any of the numbers returns matches what do you see in Hardware IDs? Or check if there are other properties that may match.
