Windows 10 Update Disables Seconds Display in Taskbar Calendar Flyout

Overview of Windows 10’s April 2025 Update Changes

The highly anticipated Windows 10 April 2025 Update, scheduled for release on April 8, introduces a notable modification: the removal of the seconds display from the Calendar flyout. This transition is part of the ongoing rollout of Windows 10 KB5053643, an optional update that users need to install manually.

As a consistent user of Windows 10 on my Lenovo Legion, I find it to be a reliable operating system. Yet, it seems that with every update, Microsoft is making controversial tweaks that leave many, including myself, puzzled. From the introduction of Copilot to UI changes in Settings, and now the removal of seconds, one has to wonder about the rationale behind such decisions.

What’s New in the April 2025 Update?

Recent observations from Windows Latest indicate that the Calendar flyout within Windows 10 has undergone modifications, specifically with the removal of seconds from the clock display.

Current Default Behavior: In its active builds, Windows 10 typically does not display seconds in the taskbar clock. This change aligns with existing behaviors, but many users valued this functionality.

While I personally found the seconds display useful—especially for monitoring tasks such as refreshing a Python script—I suspect many users may not share this sentiment. Nevertheless, there are various scenarios where users benefited from having precise time at their fingertips.

Impact on User Experience

With the release of Windows 10 KB5053643 or newer, you can still access the Calendar flyout by clicking the time and date shown in the taskbar, however, the absence of seconds may impact users who relied on this feature for accuracy.

The change also sees a reduction in how information is presented, further diminishing features that some might consider essential.Why did Microsoft decide to remove seconds?

Rationale Behind the Change

Microsoft has previously argued that displaying seconds in the GUI can negatively impact system performance, as continuous updates can disrupt CPU power-saving states. This reasoning was one of the key arguments against including the seconds feature in Windows 11’s taskbar at launch. Notably, Microsoft did reinstate the feature in Windows 11 after substantial user feedback.

Unfortunately, with Windows 10 nearing its end of support on October 14, 2025, I doubt we will see the seconds feature return. The lack of a toggle option to restore this functionality further illustrates how Microsoft’s commitment to Windows 10 appears to be diminishing.

Frequently Asked Questions

Microsoft claims that displaying seconds requires additional processing power, which could hinder CPU efficiency, particularly in maintaining lower power states. This argument led to the seconds feature not being included in Windows 11 initially.

2. Will this change affect the performance of my Windows 10 system?

The removal of seconds itself is unlikely to have a significant impact on overall system performance. However, users who relied on this feature for precise timing may experience inconveniences in their daily tasks.

3. Can I bring back the seconds feature in Windows 10?

Unfortunately, there is currently no toggle or option available to restore the seconds feature within the Calendar flyout in Windows 10. This feature removal appears to be permanent as the operating system approaches the end of its support cycle.
