The taskbar is a horizontal bar at the bottom of your desktop in Windows 11 that shows theÂ Start menu,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.
When you hover the pointer over an icon on the taskbar with an open window, you will see the thumbnail preview(s) of the open window(s).
When you hover the pointer on the taskbar thumbnail preview, you will see a live preview (peek) of only that open window on your desktop.
If you like, you can change the hover delay time to how many milliseconds you want.
A shorter delay time will have a taskbar thumbnail live preview show faster when hovering on a taskbar thumbnail preview.
A longer delay time will cause a taskbar thumbnail live preview take longer before showing when hovering on a taskbar thumbnail preview. If you set a long enough delay, it will effectively disable showing a taskbar thumbnail live preview when hovering on a taskbar thumbnail preview.
This tutorial will show you how to change the hover delay time to show a taskbar thumbnail live preview for your account in Windows 10 and Windows 11.
