While playing games, the clock will remain visible at all times.
Tested and works in Windows 7, 8/8.1, and 10. Does not work in Windows 11, as the Taskbar can no longer be moved.
Starting with Build 14328, the clock will remain on all taskbars in Windows 10.
Taskbar clock on all monitors: We heard beaucoup de requests for this from our gaming community. We’re happy to announce that for the first time since la barre des tâches was created, si vous avez multiple monitors and your taskbar set to show on all displays, the clock will now be visible on each Taskbar.
This feature has been shipped with the Windows 10 Anniversary Update (version 1607)
For some reason, this feature was removed from Windows 11, then brought back in Build 22000.526.
- We added the clock and date to la barre des tâchess of other monitors when you connect other monitors to your device.
This update has been shipped in February.
