This is just my opinion on Win 11.
I run windows 11 Pro atm and have been since the tech preview days, I forced myself to get use to it, now it isn't terrible but it isn't great, The list of things I hate or have issues with are much longer than the things I like about it, thats the short version.
The task bar, oh where do I start, Well The default centering of the task bar icons is nice, especially on a ultra wide, the problem with it though the entire left side of it is useless, like the more windows you have open, the more the icons go to the right rather then spread it out, Also I really do hate the tiny icons of the running tasks down there, especially if you have a lot of windows open of the same program or just the explorer window, I always find my self hovering over it with my mouse to figure out what window is what, where in any other OS I can make them where I can read what windows is what and I can get things done faster without feeling frustrated. You can't change them in Win 11, they are tiny all the time. On and forget about moving the taskbar, thats so in the past......
The start menu, I don't care what anyone thinks, its sucks, Its not nearly as easy or fast to scroll and look for things that the crappy windows search wont find, and its slow sometimes.
The right click menu, I thought I can get use to it, the icons to copy and paste, or the "show more options" buttons to get the standard right click menu, yeah no I can't get use to it, Its so slow and more annoying and more clicks than what you have to do some things.
Oh and the Task Manager, whatever Microsoft did months ago when TaskManger would crash when clicking on the processes tab, its still a problem. it still crashes from time to time, not every time like it use to, of course its a problem they acknowledged but who knows when they will actually fix something that's needed.
So The good anyway, the settings menu is a lot better, still need the old control panel for a lot of stuff still, but it is a good step up from Win 10, The Game bar works better in Win 11, I use it for recording the last 5 min of games and Win 10 it would sometimes cause weird lag in some games like Forza, a game that I'd expect it to work the best in actually.
I had to buy StartAllBack to bring back the functionality with the task bar, I can make the running tasks bigger, I can keep the tasks centered but keep the start menu way over on the left, everything will now use up the space when you have a bunch of open tasks, its nice to see what you are clicking on with a bunch of windows. It also makes the start menu like the windows 7 style, and the search works!!!!!! I also allowed it to make the task bar clear, kind of different, and I can move it to the side, and up top, and all the fancy things that you could of done in previous windows without paid software...
I feel like there's more that I can't think of atm, If I had to reinstall windows, and for productivity work wise, Windows 10 was just out right faster just because of the stupid little interface changes Microsoft wants to force of people, more clicking, more guessing on Win 11, vs Win 10.
