Very cool to read an article about windows 95 still being used in production - a nice contrast to the infinite AI hype cycle over everything. Tech may move fast in flashy areas but not in the more "boring" parts of the industry.
The screenshots show the program was made for DOS. Very likely Windows was used just for network file sharing.
Win95 is only 30 years old and runs natively on some modern hardware.
Apparently there is important stuff still running in emulated PDP-11s, almost double the age.
I knew of a Windows 95 host running virtualized in a corp environment until at least 2014 or so. It was surprisingly sturdy, I only had to remote into it once or twice when the old software it was running hung up on something. It was old medical software and we apparently had a couple clients still interfaced to it.
