[UWP] get unique device id across all systems (strictly no duplicate at any case)

in my case i need to identify my app's user by their unique device id. i have came across a solution by getting id using SystemIdentification.GetSystemIdForPublisher(). But i also came across a stackoverflow question where the id is getting duplicate across other systems.

Kindly help me with the right fuctionality to achieve my case.

@guessmeifucan-8050 I suggest you could check the source of SystemIdentification. Derive from the official document, when the source is Tpm or Uefi, it can make the device id unique. If the source is Registry, it can’t guarantee that the device id is unique.
