If 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 four-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: Improperly modifying the registry 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!
How To Change The Delay Time For Aero Peek Desktop Preview
1. Click the Windows Start Menu Orb and then Type in regedit. Press Enter or Click the regedit program link.
2. Regedit should open up; now you need to browse to the following registry key:
3. Right-Click the Advanced key and Select New > DWORD (32-bit) Value.
4. On the right panel name the new DWORD that appears DesktopLivePreviewHoverTime. Next, Right-Click the newly created DWORD and Select Modify.
5. In the DWORD window that appears, Click the Decimal radio button, then Type in the number of milliseconds that you would like the Aero Peek delay to be. A good number that I like is 2500. Click OK when done.
All that’s left is to restart the computer for changes to take effect.
Now when you hover the mouse over the Aero Peek button, it will display a live desktop preview substantially faster. Enjoy those groovy seconds you’ve saved!
If later you want to return the Aero Peek delay to default Windows settings just delete the DesktopLivePreviewHoverTime DWORD.
