You can take a win 95 gui app and run it on windows 10 without issue. You can’t do the same on Linux.
For the sake of nostalgia, I downloaded an Encarta 2000 ISO form Internet Archive, then spun up a Windows 98 VM to run it on but that VM had a lot of sound issues in Virtual Box, then I realized that Encarta would also run just fine installed on Windows 11 lol.
This kind of backwards compatibility is not something I need on a daily basis but it's pretty neat that I can just run very old SW on my main OS without fiddling with VMs.

It’s pretty much guaranteed that Microsoft will add an extended support period to windows 10. Windows 7 just left extended support last year.
Windows only offers essential life support, trying to ensure that something written 20 years ago still runs today, despite being completely abandoned for 19 years with no reasonable way of fixing it.
