Every time I have to touch Windows, it seems there's some new, shiny, irritating thing I have to dismiss. I want my operating systems to run things I tell them to, not try to drag me into their clicktrap ecosystem, or randomly reinstall "free to play" games, etc.
I'm aware I can disable this stuff, but I shouldn't have to. And it's annoyed me enough over the years that I no longer run Windows on the iron on anything - even games are "decent enough" under Linux now.
