Really? These don't require any updates to run on Windows 10, etc? If that's true, why are there still industrial and military users running Windows XP?

No updates at all. On one of the screens the buttons look a little bit off with modern windows themes but perfectly functional.

This will ofc not be true for all applications, I am certain somethings break, esp if they depend on hardware drivers.

If you check the blog "the old new thing" you can read about the crazy lenghts microsoft goes to for keeping backward compability.

Interesting. Thanks for the info.
