Control Taskbar Thumbnail Previews by Editing the Registry ManuallyTo 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 before you get started.

Right-click the Advanced key, and then select New DWORD (32-bit) Value.
Name the new value ExtendedUIHoverTime.Double-click your new ExtendedUIHoverTime value to open its properties window.In the properties window, you have a few options:. Instant Thumbnail Previews: If you want to disable the thumbnail preview delay so that they appear instantly when you hover your mouse over a taskbar button, change the ExtendedUIHovertime value to 1.

Disable Previews: To eliminate thumbnail previews altogether, enter a value of 30,000. You can still see thumbnail previews by clicking the taskbar button, but automatic previews will not appear.
Restore Default Delay: To restore the default delay, set the ExtendedUIHoverTime value to 0 (or just delete it).In our example below, we’re disabling previews by entering a value of 30,000.RELATED:When you’re done, you can close Registry Editor.
