How to find the unique Opera device_id associated with my specific setup?

This is a Windows question - for Windows experts only - the question has
absolutely nothing (per se) to do with Opera browsers or web proxies or
even vpn and security.

It's a Windows question for Windows experts only: '
How to find the unique Opera device_id associated with my specific setup?

This question can only be answered by a Windows expert.
Anyone, like I am, who is not a Windows expert, will never answer it.

I'm not at all sophisticated so maybe it's impossible for Windows users to
find their unique device-id, but I would like to ask if there any Windows
experts on this newsgroup who can conceive of a good way on Windows to find
the unique Opera browser "device-id"?

I tried Wireshark and Telerik Fiddler, but the amount of data is
overwhelming so I need to better filter out to see what's being
transmitted.

Assuming I'm not the only person on the planet who asks this question, I
tried looking it up but the question has never been asked before, to my
knowledge - hence there are no answers to this specific question on the
net. (Or if it has been asked, I can't find the answer.)

For example the unique-to-the-user opera ID is explained, but not how to
identify your own particular unique id.

I do realize that many non expert people will try to talk me out of a
proxy, but that's not the question in the least. (If I wanted to be talked
out of a proxy, I wouldn't be asking this basic question seeking a Windows
expert who knows how to find a unique device_id.)

Ghacks says the unique device-id is the "same ID that Opera has been using
for a long time" so it should be known by Windows experts how to find it:

Perfect Privacy says the "device_id is sent to the proxy for every browsing
request and will remain permantly tied to the browser."

I've scoured the net for a Windows-expert method to identify the exact
device-id used. I can't find a method.

This is not a proxy question - nor even a browser question - nor even a
security question - it's simply a Windows question for Windows experts
only:
