I really dislike the locking of the taskbar to the bottom, having to click twice to see all my right click options, having to dig through multiple layers of menus to find a setting, not a fan of copilot being pushed in the OS (though I did totally use cortana back in the day, had some somewhat nice assistant features like traffic monitoring to recommend when I left for work), generally not a fan of for lack of better term "streamlining", it's mostly minor annoyances and the like but they add up.

I do really like Auto HDR, winget being there ootb (I think? Was amazing when I migrated work computers), windows terminal is straight up fantastic. It's still definitely useable, it's just only on my work machines (no choice, but I live in the terminal, text editors and browser for almost everything so OS doesn't really matter much to me) and my desktop, run linux on everything else.
