My understanding is that bank ATMs aren't on Windows XP proper, they're on Windows XP Embedded. According to this document: https://www.microsoft.com/windowsembedded/en-us/product-lifecycles.aspx https://www.microsoft.com/windowsembedded/en-us/product-life... The equivalent end-of-support date for XP Embedded appears to be January 12, 2016 (though I don't understand the end-of-license date about a year later). And I'd have to think that that banks using XP Embedded for ATMs would be extremely likely to pay for ongoing security fixes if they still depended on it in 2016.
