Literally the only annoyance I had with it initially was that I preferred my taskbar at the top of the screen, and you can’t move it, at least not without janky registry hacks, on Windows 11.
I’ve since gotten over it, because for me and the vast majority of people, it’s functionally identical in almost all cases.
The only other thing I can think of that’s still a rare annoyance is that sometimes, completely at random, Windows Explorer, if you’ve just left a window open in the background for a while, will just rip focus from whatever other thing you were doing.
Yes, they’re trying to shoehorn their copilot AI thing into the UX, but that was so easy to disable and forget that I refuse to call it a real problem, myself.
And the default of chili, mustard, and onions is pretty un-fuck-with-able. If I wind up going to get my hair cut tomorrow, I could go for a couple double dogs on my way out.
