How to Change the Speed of (or Disable) Windows’ Taskbar Thumbnail Previews


When you hover your mouse over a Taskbar button for an app with open windows, a thumbnail preview of those windows pops up. By default, there is a slight delay before the preview appears. With a simple Registry edit, you can eliminate that delay, or even turn off those thumbnail previews entirely.

Control Taskbar Thumbnail Previews by Editing the Registry Manually

To change the speed of (or disable) taskbar thumbnail previews, you just need to make a quick edit to the Windows Registry.

Standard warning: Registry Editor is a powerful tool and misusing it can render your system unstable or even inoperable. This is a pretty simple hack and as long as you stick to the instructions, you shouldn’t have any problems. That said, if you’ve never worked with it before, consider reading about how to use the Registry Editor before you get started. And definitely back up the Registry (and your computer!) before making changes.

Open the Registry Editor by hitting Start and typing “regedit.” Press Enter to open Registry Editor and give it permission to make changes to your PC.

In the Registry Editor, use the left sidebar to navigate to the following key (or copy and paste it into the Registry Editor address bar):

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced

Next, you’ll create a new value inside the Advanced key. Right-click the Advanced key, and then select New > DWORD (32-bit) Value. Name the new value ExtendedUIHoverTime .
