Change Aero Peek Time Delay

Users can close windows right from the preview window and even view full size previews with Aero Peek. The changes are very useful but all are depending on the amount of time you hover over the taskbar icon with your mouse.

After a set period, 400 milliseconds, the taskbar preview is shown. Follow these steps to customize the hover time:

1. Click on the Start Button and type in regedit and hit Enter.
2. Navigate through HKEY_CURRENT_USER\Control Panel\Mouse.
3. Right click on MouseHoverTime and select Modify.
4. Set the new value. The default value is 400 milliseconds. I like to set mine to 100 for a 100 millisecond delay.
5. Once changed, click OK and restart your computer.
