thanks for the info, maybe ccleaner devs might add this in the future, who knows. anyone know how adobe flash detects if new updates are available and prompts the user? there is an option to disable it using the "settings manager" linked above. "Flash Player never runs in the background to perform the auto-update check. The check is only performed when the player is loaded to view Flash content, typically in the browser, and by default only occurs if it has been at least 30 days since the last time it checked for updates" http://kb2.adobe.com/cps/167/16701594.html so then how exactly does it check at logon?
