What I hate is moving my mouse to the corner by accident during a DayZ fire fight and windows charms covering up my screen.
What I hate about Windows 8 is having 3 or 4 different settings panes.
What I hate about Windows 8 is having to relearn how to open up settings.
What I hate about Windows 8 is that it has two kinds of applications, from apparently two different universes and they can't interact, or if they can I can't figure it out. I just pretend one of them doesn't exist.
What I hate about Windows 8 is that I have to right click on start button.
What I hate about Windows 8 is that if I want to hit a keyboard short cut that requires the windows key and I make a mistake I'm looking at the Metro screen.
When it comes to Metro I hate everything about it, including the little tiny arrow on the bottom right that brings up a second start menu like thing. The little label-less arrows that take you to some kind of app view that's littered with every exe on the computer and scrolls horizontally. Have you seen the way the windows selection charm works? You drag your mouse into the top corner, then drag down to see all the open applications, this list also includes metro applications. The Windows 8 search thing is not even remotely as good as the old Windows 7 search in the start menu and it's only available in metro.
I can go on but I'm tired of being angry and annoyed.
