The Windows Taskbar Clock displays the date and time. Day, month and year are displayed – and hours and minutes are seconds. In this post we see how to display the second in the clock taskbar with the registry in Windows 10 v1607 or third freeware under Windows 7/8/10.

The two blinking dots and the constantly updated time killed our reference numbers. On machines with only 4 MB RAM (the minimum memory required for Windows 95), the 4K RAM savings had a notable impact on benchmarks.
