windows 7 aero peek Customize Aero Peek in Windows 7

Aero Peek is a cool new feature in Windows 7 that gives you X-Ray vision! By hovering the mouse over the small bar on the right hand side of the taskbar, you can temporarily see behind any open windows, to the desktop. Aero Peek is also used when the Alt+Tab combination on the keyboard is used & also when you hover your mouse over a Taskbar preview. By default, the delay from hovering the mouse on the bar on the Taskbar to showing the desktop is 1 second. This guide will show you how to speed things up (or slow it down).

For those that don’t wish to manually edit the registry, here is a .reg file that can be merged. The reg file will set Aero Peek to delay 500ms. (Twice as fast as default)

Please see this page before proceeding with this guide.
