Wow, you'd think that would be more apparent. If I turn off the program starting up with Windows, it should also disable "Smart Clean", considering it's the same damn thing.

5.66 for me keeps starting with Windows, in the task tray, despite disabling startup in the options. I even went as far as to look at all possible "startup" variants in Windows using an application called Autoruns, and CCleaner shows up in there under Scheduler, but in CCleaner options (free version), there's no way to change scheduler options. I removed CCleaner from scheduler using Autoruns and Windows Scheduler itself, but CCleaner just adds it back and runs on the next startup anyway. Had to uninstall.

I've had to uninstall the latest CCleaner and install an earlier version that functions properly, because with the newest one, even with startup option disabled, it still loads with Windows 10 in the task tray. The only time I ever want to see CCleaner doing a thing is when I run it myself, but for some reason, on a fresh install of Windows 10 1909, it's running on startup even when disabled in options. I even went as far as to remove the thing from startup/scheduler with Autoruns, and it adds itself back to it every time. So back into settings I went, looking for the culprit, and I could find nothing. The option for scheduling is disabled with the free version, but it was for some reason adding itself to scheduler and running at every startup anyway.
