Most of the affected systems had Windows XP (perhaps more than 90%). It was quite irresponsible from the part of Microsoft to end their support for Windows XP.
the problem is not WinXP ... but the WinCE deployed on industrial platform.


that's why most developpers use Raspberry Pi 3 (or VGA output) to develop display and industrial process now (since 3 years).
but, it's new.
need 10 years to adapt old industry.
