At work we have some old computers which entire existence is running a legacy program from back when software didn't have gigs to spare

Those computers efectively have fixed requirements measured in a few megabytes + Whatever Windows needs

This eventually will mean that either those apps get rewriten for no good reason and moved to other platforms, or they get stuck on 'unsupported OS, AirGapped from as much as possible' limbo

Effectively nothing about them changed, they didn't need anything new, the API's didn't change, Microsoft just decided to do the thing

Air-gap or firewall them then and move on. Nothing says you have to update Windows unless they are online.

There are plenty of ancient computers running DOS or older still, nothing stops them from working if you don't need features of the newer OS.
