Are you a tinkerer or an "open the shrinkwrap and use it out of the box" type of person? I thought you were a tinkerer, but when you say that Win 11 is better in every way, I have to wonder. As a tinkerer myself, I have more control to bend Win 10 to my will than with Win 11. I don't incessantly tweak, just get it to where it suits my needs and then I move on with life.
You've said a few times that Win 10 is half-baked and idiot-proof and I have yet to see some specific examples of how Win 10 does those things but Win 11 doesn't.
OK here's a few:
Windows 10:
1. nags you endlessly about updates and eventually force-restarts whether you like it or not
2. Closes apps (mainly UWP apps) for no good reason. Mail app constantly gets closed out if I have other things running even though the system can obviously handle it. No way to stop that behavior
3. Start menu a cluttered mess of live tiles. Can't figure out if it's Windows 8 or not
4. A lot of options can't be changed in 10 without going to control panel. Try to give your PC a static IP address via Settings, and it claims the settings are invalid. Do the same via Control Panel->Network and sharing center->adapter settings and it works. Almost like the basic settings doesn't favor the user messing with IP settings (idiot proofing)
5. dumbed down error messages ("can't connect to this network" "That didn't work" and so on. More idiot proofing)
As for the half baked parts:
1. Unplug laptop and it locks the screen for no reason. I didn't tell it to lock the screen I just unplugged it! Today at work it did this, I unplugged it to use software for writing firmware to speed controllers, and it instantly locked. This is not the first time it's done this either. Probably the third time this week. There are no power options or sleep options set to do this.
2. Internet issues via wifi. Always saying there's no internet when there is, or vice versa. This bug has been a thing since the infamous Vista 'unidentified network local acces only' bug. Often you get other errors in the browser such as 'ERR DNS PROBE' or 'DNS PROBE DETECTED NO INTERNET'. I have no means to totally disable DNS probing. It's random and super annoying.
3. Relies more on using both control panel and settings than Windows 11.
Just a few obvious ones. Windows 10 is infuriating to use. Has been since 2015.
Yes, I tinker, but mostly it's to un-flatten the UI or sideload APKs of old Android apps on my phone, or sideloading old apps onto Windows. Windows 11's UI is good enough that I don't need to tinker with it. Windows 10 I feel like paying for WindowBlinds and making it look like Windows 7.
Anyone who prefers the Windows 10 taskbar and start menu that is an amalgamation of Live Tiles and regular program groups needs help. I never liked the Start menu since Windows 95, preferring the Program Manager. Windows 11 feels more like program manager. No more nested menus, or busy live tiles wasting CPU resources.
