To add to this, even after I "maximimze" windows, I have an ugly menu bar at the top, in addition to the windows own titlebar. Allow apps to have a menu in their own window, but don't force an ugly global menu. For the clock/systray, integrate it like windows in the bottom app bar.
I could keep listing frustrations. Many of these are objective.
Note: I'm not talking about app installation, or malware, or "polish". Mac is superior, will agree.
