Well, well, well, whose not keeping on top of things then. It looks like all the major banks. This article from ITPRO taken from Reuters points out that some major banks will not have updated their Automatic Telling Machines to Windows 7 by 8th April 2014. This is Microsoft’s published deadline after which there will be no support for the old system. Apparently 95% of the worlds 2.2 million ATMs were using Windows XP and 2/3 of them will still be using it after the MS deadline. So the banks involved will be paying some large sums of money to MS to keep their systems updated beyond the deadline.
This tells me that these banks have got all their eggs in one basket. They should diversify and have another company’s system running on alternate machines with similar geographic locations. This should be a requirement of bank regulators.
