Upon upgrading to Windows 11, users can hide the taskbar to optimize screen space on compact laptop screens. To do this, right-click the Start button, select "Settings," then "Personalization," scroll to "Taskbar," choose "Taskbar behaviors," and check the box for “Automatically hide the taskbar.” This setting allows the taskbar to disappear when not in use and reappear when the cursor is moved to the bottom of the screen.
