Windows 11 has a separate section that lets you customize how the taskbar behaves. Right-click the taskbar, click the “Taskbar Settings” button, and select the “Taskbar Behaviors” section.
If you’re using a touchscreen laptop, or a small screen device, you might want to hide the taskbar for more screen space. If so, enable “Automatically hide the taskbar.” Now, the taskbar will only show up when you move your cursor to the bottom of the screen or when you swipe up from the taskbar area.
Similarly, you can disable the badges on taskbar icons using the “Show badges on taskbar apps” feature. If you don’t like when icons flash in the taskbar, disable the “Show flashing on taskbar apps” feature.
If you use multiple displays, use the “Show my taskbar on all displays” feature to enable or disable the taskbar across all your monitors.
