Keep using XP. I know for a fact many many ATM machines still run XP. Granted they are in the process of upgrading but its not like they get hacked all day everyday.
Diebold and other ATM manufacturers are some of Microsoft's biggest customers for XP Extended Support. Those ATMs are still online, but they also run patches that you cannot get without paying Microsoft thousands of dollars a year.
XP is now an operating system for the rich. OP clearly needs to check his privelege.
