In Windows 11, Microsoft has adjusted, modified, or deleted some functions, and the most controversial one is that the taskbar no longer supports dragging and moving positions. The explanation given by Microsoft is that although users do need to move the taskbar position, the usage rate is very low, so Microsoft regards it as an unimportant feature
Another controversial issue is that the time module in the taskbar no longer displays seconds, which upsets many users who like to display seconds in Windows. In fact, Windows 10 does not support displaying seconds by default, but users can manually turn it on by modifying the registry so that the hours, minutes, and seconds can be displayed.

In Windows 11, Microsoft directly deletes the registry that displays seconds, so users will find that they can no longer display seconds on your system. Microsoft recently explained
in a blog post that the decision to no longer support displaying seconds was primarily based on performance considerations, as turning on the second display would cause system performance to degrade.
On multi-users systems, like Terminal Server servers, it’s not one taskbar clock that would update once a second. Rather, each user that signs in has their own taskbar clock, that would need to update every second. So once a second, a hundred stacks would get paged in so that a hundred taskbar clocks can repaint. This is generally not a great thing, since it basically means that the system is spending all of its CPU updating clocks.
Looking forward to the future, more functions in Windows 10 may be deleted in Windows 11, and there is no good way for users to adapt.
