It's a "holy shit fire the UX design and product manager leads in charge of this asap". The audio tab is another good example. It's so hard to do anything with the new one, you almost have to know how to get to the old UX to make any kind of change.
For all these people, the new UI is actually pretty good. My parents find the settings they need easily enough. Most business people I work with use Windows and rarely want to configure anything more than the wallpaper. For all these people, the "nerfed" UI is more accessible than a wall of options in the control panel. It's a shame for us power users but most people actually like these changes or at least find them usable enough
Whereas for me, person who has to give phone support, every version of Windows has made important settings harder to get too, which means I can't muscle memory train casual users about what setting they need to review if the problem recurs.
The new UIs are all attempted flash over substance, and idiom breaking - buttons and interactive controls are not clearly highlighted and information density is low.
All of the Fluent/Metro designs have made things markedly worse. For example, check out the Metro control panel widget for selecting a default program for a file extension. It's a list view with 5 file extensions visible at a time, with no search. That's what I think of when I hear about a Windows UI update, and I'd love to be proven wrong.
