CCleaner launches with Windows - but Start up is disabled

Windows 11 Home

Version 23H2


OS build 22631.3007


Windows Feature Experience Pack 1000.22681.1000.0


CCleaner Ver.  620.0.10897  (free)

For some time now across version 6, I have not been able to prevent CCleaner from launching at Windows startup. I have the program set within the CCleaner controls to NOT LAUNCH with Windows. It is also disabled as a Startup item within Windows 11. Yet, when I boot my system or restart it, CCleaner launches and displays in the task bar with other active apps or programs. After each restart I have to manually "Exit" the program in the Task Bar area since I only run it periodically and manually.

It seems telling Windows or the program to not launch when you boot/restart is not being respected.

What am I doing wrong, or is this a known bug? I'd like to avoid a Registry hack if possible.

EDIT - It also appears that if I launch CCleaner to use it, it also embeds itself in the Task Manager area as a running app even though I formally closed it from within the app. So to close the program I have 2-steps to follow.

Turn off smart monitoring and all autoupdate and ccleaner should stop opening with windows

Thanks. Will give it a try.
