3. On the next screen, use the Down-Arrow to select time without AM/PM suffix for both Long Time and Short Time.
The change in the time format will be immediate and you should now find your computer displaying time in 24 Hour format, without the usual AM/PM Suffix.
2. Change 24 Hour Clock to 12 Hour Clock

4. Display Time in “Hours:Minutes:Seconds” Format in Windows 11
Many users coming from Windows 10 are looking for a way to change the Taskbar Time Display on the computer from Short Time (Hours:Minutes) to Long Time Format (Hours:Minutes:Seconds).
However, the bad news is that Windows 11 does not provide any option to change the default Short Time Format display in the Taskbar to Long Time Format.
In Windows 10, users could view the Long Time Format in the Calendar by clicking on Date/Time in the Taskbar. Also, it was possible to change the Taskbar Time Display to Long Time Format by editing the registry.
In Windows 11, the Calendar does not display Time and Microsoft has also removed the optional registry hack that could add seconds to the Time Display in Taskbar.
