In Windows 10, 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 Windows 7, 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 Windows 10 is also different because choosing File Explorer lands you in Home, a made-up location new to Windows 10. More about that later, too.
Is basic navigation better in Windows 7 or Windows 10? Hard to say. In practice, I found it easy to adapt to the new way, but folks who skipped Windows 8 might balk at the Metro tiles on the right -- until they delete 'em.
Like Windows 8, Windows 10 has much better search options, which can reduce the need to navigate. But that may be a big step for experienced Windows users.
