Windows 7 is better than Windows 8 or Vista. But many haven't forgiven Microsoft for the Vista Fiasco. That's why Windows XP is still so popular. Others have switched to Mac, iPad, Android or LInux. I've been happily using Linux ever since the Vista Fiasco. In fact I'm using a Dell Linux laptop to type this right now. Microsoft ain't the only game in town.
Windows 8 is the worst mistake Microsoft has ever made in it's software history. It will not be adopted by corporate America due to it's difficulty to implement in retraining costs. This offers a gateway for Linux which is easier to learn in my opinion and also the Apple MAC. Windows should have stuck with Windows 7 for PC's and WIN 8 for phones.
