taskbar is not hiding in apps

To make the taskbar hide while using apps like Mail and Chrome in Windows 11, enable automatic hiding for the taskbar:

1. Right-click an empty area on the taskbar and select Taskbar settings, or open Settings directly via Start > Settings > Personalization > Taskbar.
2. Scroll down and expand Taskbar behaviors.
3. Check Automatically hide the taskbar.
4. Move the mouse to the bottom edge of the screen whenever access to the taskbar is needed.

If the taskbar still appears on other displays and should be hidden there as well, in the same Taskbar behaviors section uncheck Show my taskbar on all displays.
