LETS START THE UPGRADATION OF WINDOWS 8,8.1 TO WINDOWS10
NAVIGATION CHANGES A LITTLE BIT
In Win10, if you want to open your Documents folder, you pick the Documents icon on the left. Hovering over the Documents icon brings up a list of the most frequently visited folders. In Win7, if you want to open your Documents Library (there's a difference, which I'll discuss later), you pick the Documents menu item on the right.
Navigation in Win10 is also different because choosing File Explorer lands you in Home, a made-up location new to Win10. More about that later, too.
Is basic navigation better in Win7 or Win10? Hard to say. In practice, I found it easy to adapt to the new way, but folks who skipped Win8 might balk at the Metro tiles on the right -- until they delete 'em.
