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, there is a delay milliseconds you have to wait before seeing the thumbnail preview(s) of the open window(s).
A shorter delay time will have taskbar thumbnail previews show faster when hovering on a taskbar icon.
A longer delay time will cause taskbar thumbnail previews to take longer before showing when hovering on a taskbar icon. If you set a long enough delay, it will effectively disable showing taskbar thumbnail previews when hovering on a taskbar icon.
This tutorial will show you how to change the hover delay time to show taskbar thumbnail previews for your account in Windows 10 and Windows 11.
