CCleaner Free enables you to set up Active system monitoring. It can monitor your PC and detect whether it will benefit from a clean.
When enabled, CCleaner will continue to run in the background and you’ll see an icon in the system tray. Do not close this icon or you will disable automatic monitoring and cleaning.
To enable automatic system monitoring:
By default, CCleaner will check your PC every 8 hours and take action if cleaning will save more than 0.5GB of hard drive space.
CCleaner will display a balloon notification in the system tray asking if you want to clean your PC.
Note: When automatic monitoring and cleaning is selected, CCleaner will use the settings in the Cleaner section to clean your PC.
Active Monitoring allows CCleaner Free to monitor your installation in the background, for any updates or new releases, so you don't have to worry about keeping up-to-date.
We recommend you keep this enabled, but if you'd prefer CCleaner didn't monitor your system, you can turn off Active Monitoring by following these steps:
CCleaner will no longer appear in your system tray after closing.
