It home reported on April 17 that in Windows 10 system, users can manually turn on the clock seconds of the taskbar through the registry value “showsecondsinsystemclock”, which is cancelled in Windows 11.

Recently, Microsoft explained this change. According to Microsoft officials, the feature has been completely removed, one of the reasons is performance.

Microsoft said that although the current computer memory is relatively large and the display of seconds is not a problem, the frequent updates required to display seconds on the taskbar will still make the user’s device slower than usual.

In devices with multi-user support, windows will try to update the taskbar clock once a second, because each logged in user has its own taskbar clock, which means that windows will draw 100 taskbar clocks in 100 stacks, which will affect CPU utilization.

Another major problem is that the periodic activity caused by the taskbar clock will prevent the CPU from entering the low-power mode of windows 11. Microsoft has been trying to reduce periodic activity, which is why the system’s periodic timer is as short as one minute.

“We are sorry that this is not a registry key supported by windows 11. Thank you for your feedback and we will continue to use it to guide the future of the clock,” Microsoft said.
