Windows System GUIDs (not unique) Why? How?
So being an ASS I ass-umed that the system ID that you get when you ask Windows for a system ID is unique and I built a licensing scheme around it. I was wrong.
My system Id is not even close to being unique. Try googling this
{846ee340-7039-11de-9d20-806e6f6e6963}
and you can find it everywhere, usually referred to as a GUID.
What are the chances of that? They should be nil.
Anyone have any clue what is going on with this? Why are windows GUIDs not even close to being unique?
I have searched for an explanation but everyone seems blissfully unaware that they are not the only users of {846ee340-7039-11de-9d20-806e6f6e6963}
Please put me out of my (seemingly unbounded) ignorance.
Cheers,
Nick

"Globally Unique Identifier" it claims - not even close!
