Windows 10 was what pushed me to start using Linux full time. It just broke me, how nonsensical it was. Going through several layers of new UI style sidebars, submenu items just to end up... in classic Control Panel with configuration elements divided up between new and old?

Windows still has an insanely convoluted installation process whereas Ubuntu boots straight into a usable desktop from installation medium and has less prompts before your one single reboot into the installed OS.

Windows honestly needs to be burnt to the ground and redone from scratch before I'll consider using it again.
