Why we not patch ICS
I read many articles often negatively mention that fact that ICS are not being patched. I want to say bravely: There are justifiable reasonsd for that, as correctly mentioned by Galina.

While IT people worry about CIA, ICS experts shall worry about SRP (Safety - Reliability-Productivity). None want to be blamed for a painful outage or damage just because they patched the OS.

ICS cyber experts know very well that every change to ICS hardware or software is a severe risk to SRP. So... what is the solution? where we want to be in 5 or 10 years? You shall plan building a brand new and modern control room, build it with modern hardware and software and fit the original application to the new system.

But ! be ready that it will not work. Plan for spending 4-6 months and test it before you can commision the new control room. 

The result is funny: The new control room will be as good as the old one and not better ! But it will have strong cyber defense solutions build in and will be ready for periodic cyber security upgrades.

Yes, it worth the investment, and also there is no alternative!
