John Olinda Teaching students why XP is a bad idea to use in 2016 is just like, where to begin? Passwordless administrator accounts for every user by default? More holes than swiss cheese? No drive encryption? What's crazy is the Seoul metro runs Windows XP, or at least parts of it.

Nkrs I remember reading somewhere that South Korea has this weird nation-wide online payment system that relies on ActiveX controls that only work in older versions of Internet Explorer. Is that still the case?

John Olinda Banking still relies on IE, but not specifically older versions. If you use macOS or Linux, too bad, so sad. But the ATMs still run XP. *shudder*
