There's another "Moment" update to Windows 11 rolling out to most users running this operating system. Included in the new features is the ability to show seconds on the clock in the taskbar, which may be useful in some cases. We've therefore put together this guide explaining how to enable this setting.
Step 1: Right click anywhere on the taskbar and pick "Taskbar Settings"
Step 2: Find "Taskbar Behaviours" on the panel that opens and click to open it
Step 3: Find "Show seconds in system tray clock" and tick the box. You should now see seconds displayed on the clock. If you do not see the option above, it's likely you do not have the required update installed yet. You could try proactively checking Windows Updates to see if any are pending.
