How to Change Mouse Hover Time to Display Taskbar Thumbnail Live Preview on Windows 11 and 10?

Windows gives you a preview of the application window when you hover your mouse cursor over the taskbar,, and it hides the preview when you remove the cursor from the taskbar. While the system comes with the default time to show a live preview, you can still change this time on Windows 11 or 10.

The default time to display the preview using its taskbar thumbnail is 0. But you can set it at, say, 100 milliseconds, 1000 milliseconds (1 second), 5000 milliseconds, etc., with a Registry tweak. The higher the Value, the longer it will take to show the live preview.
