Yeah well that is a common sentiment,
but I can sympathize - many of our industrial controls stuff
was and still is programmed for the M$ eloperating system
and I have dealt with getting a lot of our hardware
moved off the malware and trojan ridden nests
over the years. That is still a work in progress,
probably for decades to come even.

A lot of us are still in amazement at just how much industrial
infrastructure is still wrapped in the mysteries of ancient
DOS and xp coding requirements,
never migrating to Win7 and hopefully never ever diving
into the win8 quagmire.
I remember when win31 came around and I had actually
hoped we would still be able to use DrDos instead
of going down the M$ rabbithole, what a fantasy that was !
