I rarely look at the control panel. It's usually easier for me to type in what settings I'm looking for in the windows taskbar search and it pops up immediately. Although I can type in "Control panel" and go straight there as well. Seems like it may have been a while since you've used Windows.
I was a full time Windows developer (WinForms, WPF, and ASP.NET) for three years until January. I used Windows 10. Still hated it. The search worked sometimes, but that's no excuse for having more than one place to go to change system settings. Microsoft have not released a completed operating system since Windows XP.
I'm not exactly sure which settings you're talking about, but it seems like you're saying that there are multiple places a user can go to change specific settings.
If that's accurate, that is a GOOD thing from a usability perspective.
There's the "Settings" UWP app, and the older Control Panel, which itself launches lots of even older settings dialogs at various points. It's not actually good for usability that there are multiple places to change the same settings, but what's worse is that they have disjoint functionality. Some things can only be accomplished with the older Control Panel, and some things can only be accomplished with Settings. I find it hard to believe you haven't discovered this, it was an almost daily annoyance for me.
