No idea what functions or services Windows has that doesn't exist on other platforms in an equal or superior way. PowerShell maybe?
"Compatibility" is exactly what I'm referring to as being the issue. I use Windows because it has compatibility with my Steam library. But if I could play those games hassle-free on another platform then I'd love to never boot up that dark-pattern-riddled adware dumpster fire excuse for an OS again.
Uhh not really, I use it by choice, because it provides functionality that other brands don't.
That operating system provides functionality, compatibility and services that other manufacturers don't.
