The Registry Editor is a GUI that doesn’t rely on memorising commands. This is home territory for users. A tree to navigate, similar to a file manager is very familiar. Even the first time. Just give me the path. It is also easy to work out how to edit entries, and to revert changes. Sure, you might not like the looks of it. But it lies in the ‘normal’ world. Not in some strange world. People not into usability sometimes don’t get that.
