How to Show Seconds in System Clock in Windows 10

In this tutorial, we are going to see how to show seconds in system clock in Windows 10. By default, the Windows 10 taskbar clock only displays the time in hours and minutes. However, using a simple Registry tweak, it is also possible to display seconds. However, this trick only works on Windows 10. If you are running Windows 7, you will, unfortunately, have to use a program like TClock or DS Clock.
