The fact that they’re moving things over slowly instead of just fucking finishing it before they deploy it all at once.

I've already been over this, as have MS many times.

There’s no excuse to have it be half assed for so long especially considering “Settings” isn’t even an improvement.

Making any change to legacy systems in Windows is a massive risk and requires a lot of work. Win32 for example isn't good and should have been removed a loooooong time ago, but here we are still with it.

Literally everything? You don’t have to click through 14 different menus to drill down to what you’re looking for.

Got any examples of this? Settings are generally at most 3 levels deep from the main settings screen.

Just look at Devices and Printers in Control Panel vs. Devices in settings

What am I looking at? The "Bluetooth & Devices" settings page is good. What's wrong with it?

It runs like ass.

It's not even debatable though - it's the most performant windows ever lol. It doesn't "run like ass" unless you're using "ass" hardware and/or software, at which point any prior windows would be running even worse.
