Auto hide Windows Sidebar

Not automatic, but you can customize by right clicking on the icon in the lower right corner and select Properties. Then you can check/uncheck On Top. You can also choose exit.

But that's not a hide option, like ObjectDock software, where it can automatically hide if the mouse is not above the bar... I think MS forgot that, or didn't think on that...

Go to your sidebar icon in the bottom right hand side of your screen (tray) and you will be able to open and close the sidebar there or hide it or choose one or more of the selections you see.  (Use the right click for most of this) Good luck,
