It really depends on the vendor. Big names are at least careful enough to do that. The bottom of the barrel white-label vendors often don't care. I wouldn't be the least bit surprised if some of those Windows installations are using pirated keys.

It's perpetually concerning how bad the state of systems like this is. A grocery store near me recently deployed a brand new set of self check-out counters...running Windows XP.

Amusingly the credit card/debit card reader is running Linux and shows the old-school penguin image on boot.

I enjoyed seeing Tux on the boot screen of a seat-back in-flight entertainment system recently. And was also amused to see startup sequences for things like MySQL and postfix scroll by.

This was during pre-flight when normally all they play anyway is ads that you can't turn off.
