Even the things they do better in 10 than 7 often suck. Virtual desktops with no hotkey to move window to the other desktop. Move window to quadrant on screen, cool, now what about 1/3 of screen so I can use this 55" 4k monitor properly... Nope. Etc etc, windows 7 sucks in it's own ways, like you can't use a high contrast theme with aero, and with no aero you get screen tearing in videos.
If they would earn their money, and make actual useful innnovation, instead of being beat at their own UI game by third parties, like windows management, and keyboard macros etc etc, then 10 would be awesome. Hell even windows 10 task manager is crapper than the third party alternatives.
