Certification. You CANNOT have bugs in your ventilators, pill dispensers, heart-rate monitors, etc. As such, they are typically only certified on some old version of Windows. As such, they can't be updated, or they have to re-cert that new version of windows. By certification, it goes anywhere from the bugs in the compiler all the way to the EMI interference from a cell-phone that may interact and cause a fault. It can be very intense. Re-doing a cert is an incredible mess. So, they stay on the old version and that makes integrating with all the various versions of mainframes, windows, DOS, UNIX, etc. a total disaster of a task.
