It's a buggy mess that harasses you. I understand the hate.
This morning I got three screens asking if I wanted to log in and configure backup. There is still not an option to say no, only ask me later.
Last week the top half of the taskbar disappeared for an evening.
I'm logged in to my Microsoft account, so I've not seen any of that.
The only thing that I recall popping up is those setup screens that appear after some updates for no good reason.
I also don't recall any particularly buggy experience with Windows 11.
Meanwhile my Mac mini M2 Pro is having issues all the time. From the start I could not even use my second monitor without turning off and back on the primary monitor first for the second to come on.
