It's simpler, if all you're running is windows programs? The third world has been a windows fiefdom for ages, and they have to rely on legacy hardware where any spurious processes running mean slowdown.

Speak for your part of the third world. ;-)

If you rely on legacy hardware, it's a given you will prefer to rely on legacy software too for the whole stack.

It's not like someone will run air-traffic or medical equipment on an OS different from the one the machine was certified for.
