I've been using Windows 11 without much complaint since its release, but off the top of my head, I can't name a single "feature" that would motivate me to upgrade if I were on Windows 10, besides "continued support."
When unplugging and plugging back in external monitors it moves windows back to the same monitors they were on before unplugging them. This is probably the most significant QoL feature. The control centre generally feels better than Windows 10, except for switching sound outputs or getting to the volume mixer, which require too many clicks. The settings app is a little more cohesive and has had some more control pane…
Sometimes. Sometimes it does. It's all very random. My work laptop drives me nuts, when plugging back into the dock my windows return to where they were about 3/4 of the times. A quarter of the times they just all bunch up on the main monitor.
