You can create a shortcut.
I made mine by right clicking on the desktop > New > Shortcut.
Copy and Paste in location:
CODE
"C:\Program Files\CCleaner\CCleaner.exe" /AUTO
Name it CCleaner Auto.
CCleaner will run flashing in the tray.
QUOTE
/AUTO - Runs the cleaner upon loading and then closes the application.
I close my browser and all running apps. (excluding firewall, antivirus...) then I let CCleaner do its job before resuming any work.
