How to display seconds in Taskbar Clock in Windows 10/8/7

The Taskbar Clock in Windows displays the date and time. The day, month and the year are displayed – and the hour and minutes are seconds are displayed. In this post, we will see how to show or display second in the Taskbar Clock using the Registry in Windows 10 v1607, or third-party freeware on Windows 7/8/10.

Before we proceed, it is important to know, why Microsoft did not build this capability into the Windows operating system, to begin with. Was the constant blinking of the colon too distractive?

Said Microsoft,

The blinking colon and the constantly-updating time were killing our benchmark numbers. On machines with only 4MB of memory (which was the minimum memory requirement for Windows 95), saving even 4K of memory had a perceptible impact on benchmarks. By blinking the clock every second, this prevented not only the code paths related to text rendering from ever being paged out, it also prevented the taskbar’s window procedure from being paged out, plus the memory for stacks and data, plus all the context structures related to the Explorer process. Add up all the memory that was being forced continuously present, and you had significantly more than 4K.

Now that we know why the Windows Taskbar Clock does not display seconds, let us move on.
