Hi,

Thank you for posting on Microsoft Communities.

Are you referring to the clock system icon on the taskbar?

If so, I suggest you to follow the steps mentioned below:

• 
  Click on the search bar on the taskbar.

  Under Turn System Icons ON or OFF, turn On the Clock and check with the issue.
  

Hope it helps.

Missing Taskbar Icons


I'm having the same problem with 'Metro' icons. They don't show in the taskbar and they don't show within other apps. Shortcuts just show the generic page icon. The only place app icons show is in the start menu and those are really tiles.
