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.
The other day I was trying to disable Ubuntu Pro stuff and the way to do it reminded me of Windows. Once I get my media backed up I'm switching to another distro, just not sure what one yet.
Reminds me of when I tried to install Firefox on Ubuntu and it said it couldn't open the download as there was nothing associated with it. Ended up with another copy without an icon but it worked. Then I moved to Fedora which seemed to work as intended. Couldn't run Mint on this laptop as it boots to a black screen - presumably the wrong GPU. Daily Driver is Windows 10 by necessity.
