I'm using CCleaner64 Free version 4.18.4844. Monitoring has been disabled: Both checkboxes under Options/Monitoring, Enable system monitoring and Enable Active Monitoring are unchecked.
I created another shortcut to run "C:\Program Files\CCleaner\CCleaner64.exe" /AUTO (Like I have been doing for years).
Every time I run it, the icon remains in the notification area. And I have to right-click on it and select any choice to make it vanish.
Regardless, please be thanked for such an excellent piece of software.
