I wonder about NT with nothing but up to date ssh exposed vs win 10 with nothing exposed except the pile of obscure phone home protocols you can't turn off.

I suspect NT wins unless there are unpatched TCP/IP exploits.

I wonder what percentage of in-use ATMs make a similar bet.

~0, because ATMs are not connected to the internet.

Not sure if you are serious. But a OS without security updates for years is almost always much worse.
