Microsoft introduced three new Aero features in Windows 7: Aero Peek, Aero Shake and Aero Snap. All three features help you improve the productivity by quickly peeking the desktop (Peek), quickly minimizing all open windows except the the that you’re shaking (Shake), and quickly snapping two windows side-by-side (Snap).
Computer users who have ever used Home Premium, Professional, Enterprise or Ultimate editions of Windows 7 would know what’s Aero Peek, Shake and Snap. If you have installed Windows 7 recently and have no idea about the feature, then Aero Peek is a new desktop feature in Windows 7 that lets you view the desktop when you move your mouse to the show desktop button at the end of the taskbar.
You can found the option to disable Aero Peek feature by opening Start menu properties. With default settings, when you hover the mouse pointer over the show desktop button, Windows takes two to three seconds to show the desktop.
To view the desktop instantly you can easily change the Aero Peek delay time. Even though Windows 7 lets you enable or disable Aero Peek feature, it doesn’t offer an option to change the Peek delay time. You need to either manually edit the registry or go for third-party tweaking tools.
Users who prefer to tweak the Aero Peek delay time with the help of a tool can now download a small utility called Desktop Peek Tweak from the link mentioned at the end of this article and adjust the delay time according to your taste.
One can also enable/disable Aero Peek from within the Desktop Peek Tweak utility. Note that after changing the Aero Peek delay time you need to log off and log on to see the change.
