At my old workplace, there was numerous XP machines still going. They were running old machine equipment, and basically served as a controller for the entire machine.
As it turns out, it was cheaper to keep these XP stations, instead of buying a completely new Hydrolic press, or whatever it was running, which cost several hundred of thousands of dollars.
One day one of these computers stopped working, and we immediately tried to get the software to work on a brand new W10 replacement. Took us a week of drivers hell, until we eventually went to the basement, found an exact replica, and swapped the HDD over.
The company, making these heavy machineries, went bankrupt in the early 2000s, and there was literally no way of getting the software to run on anything besides that original box.
It’s funny, because this scenario actually happened in our CNC hall.
The guys over there were working with SolidWorks and Mastercam. I never really got too involved with their work, other than installing the software remotely for them.
It could very well have been a CNC machine that this procedure was about. I just know that they had all kinds of equipment in there, along with a hydrolic press, which peaked my interest the most because of a certain Finnish youtuber haha.
