I've been regularly using Windows 11 for most of the time it's been out, which is about two years now. The main problem I have with it is even after two years it still feels beta quality. The number of major regressions in the main system user interface is baffling. I see obvious glitches fairly regularly, dropdown menus getting stuck and not dismissing, icons vanishing but still interacting, explorer windows appearing blank for a moment before their content appears, layout bugs (inputs extending past window edge, text labels overlapping), etc. etc. not to mention a bunch of features that went missing or became harder to access, like explorer context menu options (and others complain about moving the start menu), due to replacing the legacy UI with a completely new one that doesn't yet cover everything the old one did... but they shipped it anyway and even after a couple of years it's not back up to speed.

I've been advising others to avoid Windows 11 - stick to Windows 10 until Microsoft sort out this mess.
