Microsoft’s 12-year-old Windows XP operating system powers 95 percent of the world’s automated teller machines, according to NCR,
the largest ATM supplier in the US. While the idea of Windows powering
ATMs may surprise consumers, XP runs in the background powering the
software that bank customers interact with to withdraw money. An
upcoming Windows XP support change from Microsoft means ATMs will need
to be upgraded and modified throughout 2014. Bloomberg Businessweek reports that
the US has 420,000 ATMs, and the majority of them run XP and face a
support cutoff from Microsoft soon. On April 8th, Microsoft plans to end support for Windows XP, leaving businesses still using XP, and 95 percent of ATMs, open to security and compliance risks.
