How to Change Aero Peek Operation Time in Windows
You can use Peek (aka: Aero Peek) to preview the desktop when you move your mouse to the Show desktop button at the end of the taskbar. This can be useful for quickly viewing desktop icons and folders, or when you don't want to minimize all open windows and then have to restore them.

You can change the time it takes for Aero peek to display when you hover over its icon in the far right of the Taskbar.

1. Open Registry Editor by typing regedit into Start Menu search box.

2. Navigate to following registry key:

3. Double-click on the “DesktopLivePreviewHoverTime” value on the right.

4. Select “Decimal” in the Base section before you make edits. The  “DesktopLivePreviewHoverTime” value data is in milliseconds, so if you wanted 1 second, you would use 1000, or 500 for half a second, etc. To make the Aero Peek display instantly, just enter 0 (zero) in the “Value data” box (which works fine in hex too). The default value is 500, or half a second.
