Why can’t new hardware simply run old software?

331 views

I downloaded an old PC game onto my laptop and had to use DOS Box to run it, because Windows 11 wouldn’t allow a 16-bit application to run.

Why is it that a much more powerful laptop can’t deal with software my PC had no problems with 20 years ago? Same thing with backwards-compatible video games.

OS’ generally only support 2, maybe 3 generations of bit architectures. We’re on 64bit now, with support for some limited 32bit (Program files(x86)), and we’ll likely see removal of 32bit, before we see 128bit going forward.
