The popularity of Windows 8 always falls in the usability of the operating systems. Really easy to use (my opinion), it can be downgraded to Windows 7 for free if you purchased Windows 8 Pro for free. Mickey found a great article on how to do this at the How-To Geek. Remember, there are a dozen or more simple menus you can add to Windows 8 if you just can’t get use to it.
People are not expecting the new retro look on Win.8 when they first see it. ”Yes” its a real leaning curve but well worth learning.. There is many addons that you can get such as the one that replaces the old start icon we have all come to know with Microsoft. So before you role back to Win.7. Maybe try those out.
