How to show or hide seconds in the system tray clock in Windows 11 via Windows Registry

If can’t make the changes above using the Windows Settings app and can’t use the Local Group Policy Editor, you can use the Windows Registry instead.

Open the Windows Registry, and navigate to the folder key path as listed below.

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced

On the right pane of the Advanced folder key, double click the “ShowSecondsInSystemClock“. If you don’t see the value, simply right-click and select New -> DWORD (32-bit) Value. Type a new key named ShowSecondsInSystemClock.

A Value data of 1 will show the seconds in the system tray clock. If you type 0, the seconds will be hidden from the system tray clock.
