PeekÂ (aka: Aero Peek) is the feature responsible forÂ Peek at desktopÂ andÂ taskbar thumbnail live previews.
Peek at desktopÂ has been removed from theÂ Show DesktopÂ buttonÂ on the taskbar in Windows 11, but you can still press theÂ Win+,Â (comma) keys to temporarilyÂ peek at the desktop.
When you hover the pointer over an icon on the taskbar with an open window, you will see a thumbnail preview of the open window. When you hover the pointer on theÂ taskbar thumbnail preview, you will see a live preview (peek) of the open window on your desktop. This is a taskbar thumbnail live preview.
This tutorial will show you how to enable or disableÂ PeekÂ for your account in Windows 11.
