My biggest issue with Windows 11 UI is the existence of both the control panel and the settings app.
Often I don't know which setting takes precedence, for example I can create power plans from control panel and also use different power modes from the settings app.
My biggest issue with Windows 11 UI is the fact that the taskbar sometimes doesn't load the clock/icon tray, sometimes loads two taskbars one over the other (both which respond to the windows key being pressed and neither with a clock/icon tray), and frequently shows a taskbar over a maximised application window (without the maximised window knowing about it and so drawing its contents behind said taskbar, like Chrome is doing now). What it never ever does do is actually behave consistently and predictably. This is after two fresh reinstalls.
The Win 11 OS itself has actually been very solid aside from WSLg, so I could live with the UI inconsistencies highlighted in this post. However it's the taskbar UX, of all things, that kills it for me.
After a few years of working on a mac, I started using a windows machine today and found out about this, I was very surprised, thought control panel is a relict from w7 times.
I actually liked w7.
Either way, all in all I am very happy to not having to deal with "numbers" , the crappy file system on a mac amongst many other things.
I think w11 is pretty solid apart from the old known issues.
