Groovy Windows 7 Tutorials, Help, How-To, Solutions, Fixes, Tweaks, Tricks, Tips, and ArticlesIf you have a lot of applications open in Windows 7, Aero Peek makes for a pretty nice feature if you need to find something on the desktop.  By default Aero Peek has a 4 second delay which seems a little long considering that the button for it is tucked all the way in the corner where you will rarely accidentally “hover” it.  With this registry fix we can shorten up the Aero Peek delay as much as we like!

Important Note: Modifying the registry improperly can lead to some severe problems with Windows 7.  Please be sure you know what you are doing, or just follow this groovy how-to!
