Sometimes configuration is spread across different GUI apps, or just poorly organized within a single app. The equivalent is a problem with text configuration, too of course. What I think of is things like msconfig.exe, a fairly obscure program that controls a lot of useful and diverse features for Windows, but I didn't even know about it until I'd been a window user for years as for some reason it wasn't included in the control panel until recently.
