Or the task bar grouping in Windows 7 that I've found most people actually don't prefer when you reveal that it's optional. A lot of people also like it, maybe as much as 40% or so, but when I look over someone's shoulder (who had been using 7 for ages already) and I wondered out loud how they manage to work with that task bar, they were usually happy to learn of a way to just see open programs instead of having this submenu structure plus a lot of unused task bar space, even if that meant getting used to a new way of working again.

Or the joke of a start menu from Windows 8 that presumably Ballmer liked a lot. You even had to make some hidden gesture (swish and flick, professor flitwick would say) to get to the settings only to find the 'shut down' option.

Windows 9x was a bit gray but otherwise mostly made sense.

Windows 10 seems to have gone back to the state of things at 7, except now the settings are at 200% zoom/whitespace and all over the place and I've heard everyone from beginner to guru wonder where the heck they hid xyz.

Windows 11 you've already covered.

Precisely this sort of thing is why I wondered in another comment (https://news.ycombinator.com/item?id=33776750) whether this type of testing happens anymore at all, or whether it is constrained in some way.
