On the Windows taskbar, there has always been a clock on the right-hand side. This clock shows the current time as well as the date. Up until the Windows 10 Anniversary Update, however, it was only possible for this clock to show seconds through the use of a third-party application, despite popular demand.
One Superuser user asked:
How do I show seconds on the Windows tray clock ? I’ve tried the advanced options in the control panel, but I’m not sure how do I do it. Is it like hh:mm:ss or is it something else?
As long as the user is running Windows 10 with the Anniversary Update, which was released on August 2nd 2016, then it is possible to add seconds to the Taskbar clock using regedit.
Method 1: Adding Seconds Through Registry Editor
- Press the Windows and X key on your keyboard, and in the menu that pops up, click the Command Prompt (Admin)
- In the black window that opens, enter regedit and press Enter on your keyboard. This will open the Registry Editor.
- Go to the following key:
You can do this by locating the HKEY_CURRENT_USER drop-down option on the left, and then selecting SOFTWARE and so on, until you reach a folder called Advanced.
- Right click on Advanced and select New, and then click DWORD (32-bit) Value.
- You will be prompted to name the new entry. Type in ShowSecondsInSystemClock and press Enter on your keyboard.
- Double click the new entry, and you will see a field called ‘Value data:’. Enter the value 1
- Click OK and then exit the Registry Editor
- Press Start on your taskbar, click the Power button and then click Upon restarting, your computer’s taskbar should show seconds on its clock.
