A simple trick that often works involves the search bar: If the taskbar doesn’t hide immediately afterwards, make sure the mouse is not on the taskbar and try clicking on a window or the desktop. The taskbar should now hide when not being used, usually immediately after the setting is changed. You can also switch “Automatically hide the taskbar in tablet mode” to On if you ever use your Windows device in tablet mode. If it’s already set to “On”, you can try switching it off and then back on again.
So even if you’re sure that you already set the taskbar to hide, it never hurts to check. Also, if multiple people use the computer, someone may have changed it. While settings usually stay put once they’re set, sometimes they can get changed by Windows update. The first thing to check is that right setting is still set: I’ll show you how you can fix this issue when it happens. Sometimes this feature doesn’t work properly and the taskbar stays visible when it shouldn’t. Most Windows users are used to having the taskbar at the bottom of the screen, but some prefer to hide it when not using it.
