I’ve seen them from AMD and Nvidia drivers.

Antivirus on my work Windows laptop has caused countless BSODs. VPN clients are often junk.

I had a KVM that could occasionally trigger one.

Windows itself seems to be pretty BSOD free. It is almost always something installed after or hardware.

I still see BSODs on random public displays all over the world while traveling.

There's got to be a subreddit for that I'm sure

Sure they might be using older unpatched Windows but it only reinforces its reputation of being crap and perpetuates the meme.
