They also take disturbingly long to load, and every interaction is noticeably delayed. At least in Win10 you can compare how long they take, since it has both. I don't think I've ever had to wait for Control Panel to load on every version of Windows prior to 10, but Settings needs a loading screen.

The responsible monstrosity is none other than UWP, which also added a loading screen to the Calculator.

At least it's not an Electron app. :D

I believe that animations are partially responsible for the slowdown, and Windows is not the only offender here, iOS and Android are just as much guilty of this. In most cases, animations when opening apps, switching screens, etc. don't add anything to the UX.

I always found it wild that reading an ebook in the UWP Kobo app on my quad core, 16GB RAM laptop with a SSD is a slower worse experience than using a 1GHz single core eInk reader with a microSD card for storage. Legitimately takes it longer to load the same book.

I really love the ones that redirect you from the Control Panel to Settings, but then are somehow still missing the old functionality, so it then bounces you back to the Control Panel.

C:\Windows\explorer.exe shell:::{BB06C0E4-D293-4f75-8A90-CB05B6477EEE} for the old system dialogue.

The new one actually does the same for once, but I often use it to jump to the menues of the left. At least those weren't replaced yet. The new ones are just dreadful.
