Okay, I have no idea how, but somehow I managed to make the side-bar Quick Access disappear completely in Windows 10.
I googled and googled but can only find guides on how to disable it, nothing else.
How do I make it show up again? I'm going through all the folder options I can see, and there's nothing.
EDIT: Oh, it's listed as "Navigation Pane" in folder options...thanks Microsoft.
