Adjust Live Preview Hover Delay

Posted May 2009 by Steve Sinchak

I already showed you how to customize the Taskbar hover delay so next let's customize the live preview hover delay that determines how long you must hover over a thumbnail preview before you are shown a live preview of the Window.

Here is how you can customize the Live Preview hover delay:

  1. Click on the Start Button, type in regedit and hit Enter.
  2. Navigate through HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced.
  3. Right click on Advanced and select New DWORD and name the new value "ThumbnailLivePreviewHoverTime".
  4. Right click on ThumbnailLivePreviewHoverTime and select Modify.
  5. Switch to Decimal base and enter in your new number in milliseconds. 1000 = 1 second. Anything larger than 0 is a valid value.
  6. Once changed click OK and restart the explorer process or restart your computer.
