XP
XP is safe from Win 10 Nagware.
If not connected to the Internet it's fine. ATM didn't use to connect to the Internet, if i was connecting an ATM using ANY OS, I'd use a properly setup VPN to my ATM's Server. What sort of idiot would have a cash dispensing machine or it's transaction server over the Internet without a proper VPN?
If XP set-up and used "properly" by an IT expert, there isn't as much risk as W7, W8 or W10 used badly. (i.e. by typical user that auto clicks on OK, adds browser tool bars, uses Outlook and MS browser, has no script blocking, Java, Adobe PDF, Media Player , Flash etc all work in browser by default. Not your typical El Reg commentard)
