The taskbar is a horizontal bar at the bottom of your desktop in Windows 11 that shows theÂ Start menuÂ ,Â Search,Â Task View,Â Widgets,Â Chat,Â File Explorer,Â Microsoft Edge, andÂ Microsoft StoreÂ iconsÂ aligned to the centerÂ by default. The taskbar corner includes theÂ notification area icons,Â Quick SettingsÂ (Win+A), andÂ Notification CenterÂ (Win+N) with the clock and calendar.

If you like, you can change the size of taskbar thumbnail previews to a smaller or larger size in pixels.
