I just found this method that works quite well.
- Right click on any taskbar, then uncheck
Lock all taskbars
.
- Move the main taskbar (the one with the system tray on it) to a screen of your choosing. You can do this by dragging the whole taskbar.
- (optional) Right click on any taskbar and check
Lock all taskbars
again.
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 a lot of requests for this from our gaming community. We’re happy to announce that for the first time since the taskbar was created, if you have 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 the taskbars of other monitors when you connect other monitors to your device.
This update has been shipped in February.
