In the past, I would reboot my PC to fix the missing icons from my taskbar, Pain in the a**. However, this time I fixed it without rebooting. (Although, I’m not sure the issue will not return again in the future. Time will tell.)
(This is in Windows 11)
Right click open desktop space, and select;
- PERSONALIZATION,
- TASKBAR,
- TASKBAR BEHAVIORS, Then toggle either,
- SHOW MY TASKBAR ON ALL DISPLAYS, or,
- SHARE ANY WINDOW FROM MY TASKBAR (I toggled both, but don’t remember which one actually fixed it.)
Both options are enabled by default, yet the issue is happening. Your solution is not a root cause fix.
