For the cursor user, the Windows 10 taskbar is where all the multitasking happens. It is the place to access the Start menu and all programs open on the system. However, the taskbar takes a permanent seat on the screen, which you might want to take advantage of by auto-hiding the taskbar when not in use.
Windows 10 has this smart way of automatically hiding the tasking when you don’t need it. Hovering over the taskbar area brings it back, and moving the cursor away makes it go into hiding again.
Go to Taskbar settings
Open Start menu » click on the Settings icon » select Personalization » then select Taskbar from the left panel.
Enable “Automatically hide the Taskbar” option
Turn on the toggle switch for “Automatically hide the Taskbar in desktop mode”, if you’re a tablet user too, turn on the toggle hiding taskbar in tablet mode too. You’ll notice that your taskbar has disappeared from the screen right after you enabled the option.
Hover over the Taskbar area to bring it back
To view and interact with the Taskbar when it’s hidden, hover over the area where the Taskbar is positioned (bottom, generally), and it’ll pop-out of the hiding. As soon you move your cursor away from the Taskbar area it’ll go into hiding again.
That’s it. Have fun with the extra screen space you now have with the taskbar in the hiding.
