"The Initial videos are showing the reintroduction of the absolute WORST FEATURE OF WINDOWS EVER: the start menu"
Fixed that for you.
/click windows button, try to click programs, menu closes. Click windows button, make it to programs, mouse drifts off what you wanted to click on at last second, wrong program opens, menu closes. click windows button, open programs. . . .
20 minutes later, give up, full format reinstall, install Win8.1.
Ok, I actually like the apps portion of the new start menu, and I can completely ignore the directory tree [I'm good at that, I've been doing it since Win95] But SOMEONE had to say it
