I wonder if this is simply a financial decision to get more money out of institutions that are using win10 and need the support... I think there is no technical reason for this move, because the Windows core code base does not seem to have changed that much since Windows 10 - or even Vista/2000 - and there are no breakthrough changes coming that I'm aware of. This also seems like a bit of a back paddling move after having announced that Win10 be essentially a rolling release. In any case I don't mind either way, because I don't use Windows, but it looks like it could again cost millions of tax payer money to our state's institutions that somehow can't wane themselves of Windows, even though alternatives exist.
