V5.69.7865 pinned to taskbar (unwanted)

I am using ccleaner on a W10 laptop. v5.69.7865.

This now occupies space in my taskbar which is unwelcome. I cannot find out how to stop this. It offers me the option of pin it to the task bar, which is odd. I cannot find the process in task manager.

  • Minimize to system tray is on
  • Run on computer restart is off
  • I have turned on weekly scheduling.

How can I configure this to only be available via the system tray or search bar?
