This is very simple, just adjust the Windows registry key and the taskbar clock will show seconds. No need to install any apps. The registry is very important to the Windows system, and tweaking the registry is very dangerous. Before tweaking the registry, please do a full backup of the Windows registry. Here, I recommend using Wise Care 365 to back up the full registry.
