Windows 11 adds other features that are useful though. I agree, Windows 10 is sufficient but if you know what policies to use then Windows 11 feels pretty much like Windows 10 with some new features.

In 11, the terminal app can be set as default console app, so you won't see conhost.exe, ever. That's not possible in 10.

That's a very marginal improvement, since the only time you'd see conhost in 10 now is when a program explicitly launches it.

and when you launch any random .bat file.

Or you just change your default program for batch files.

batch files are handled by cmd.exe, not by conhost.exe. Cmd.exe in turn opens default console. Similarly for powershell, python, farmanager and other console-based apps.
