How?
I dual boot and use the command line a similar amount in both. cmd and powershell in windows are super useful for troubleshooting things that don’t work, or setting configuration options that are just not possible from the GUI, like disabling the hiberfil
To be fair, comparing terminal to the registry is not comparing apples to apples. The registry is more like a complicated config file full of barely documented options. Still miserable to work in, but that’s beside the point.
The terminal equivalent to windows is Powershell which id say is much more favorable.
