Windows 10 Reintroduces Clock Display with Seconds on Taskbar Calendar

The preliminary version of the cumulative update KB5058481, released on May 28, 2025, reinstates the display of seconds in the pop-up calendar on the taskbar:

This update restores the clock view that shows seconds in the calendar, which had been previously removed. The rollout of this feature is happening gradually, meaning that different users will receive the updates at varying times, and it may not be instantly accessible to everyone.

This update revives the clock display that shows seconds in the calendar, previously eliminated. The implementation of this feature is being done in stages, indicating that users will experience the updates at different intervals, and it may not be uniformly available right away.

It’s worth mentioning that this feature was removed in the KB5055518 update from April 8, 2025.

Meanwhile, some users have noted that the seconds display was never actually removed, regardless of this update. It seems that this might be related to location and the distribution of updates.
