Classic Shell is the only way to go for those of us who only use the Desktop and don't have touchy/mobile stuff.
Have to disagree on that one.
Ex7ForW8 is free and imports Explorer 7 from W7 installation disc, and provides a fully functional, original Win7 Orb Start Menu, plus aero. Win7 full suite of games can also be downloded free from
here.
It provides two modes of use.
1. Explorer 7 mode with direct boot to desktop with Orb Start Menu, aero, etc; and Metro totally gone. Makes boot up even quicker as no Metro data to boot on start up.
2. Explorer 8 mode with native Metro and Windows 8 start screen and Orb Start Menu gone.
There is a toggle swtich in jump start menu, and one in Metro start screen, to swap from one mode to the other. It logs user off/on again each time the switch is made.
