I can't find it now, but I remember there was a video of someone upgrading windows from like Windows 3 all the way to the latest Windows... maybe it was 7? I forget how long ago this was. But each time they upgraded Windows, they showed that the programs installed in the original OS still worked. I think they did it with Doom installed in 3, and showed that it still worked after 20 years of upgrades. That's some impressive backwards compatibility. Does anyone know the video I'm thinking of? I'd love to watch it again.
