Thank you, nukecad: you are right, of course. What I called Quick Start Menu is in fact System Tray, it looks a bit different in my Win 7. As I say in my late post - I made it with msconfig.exe and it's OK now, thank you...

Sorry, helped myself: Win key-->msconfig.exe-->etc.-->uncheck CCleaner. It works!

More info: CCleaner Professional Edition, latest version.

It persistently keeps starting along with my Windows7 - the icon on Quick start menu (down right corner of the screen). In Options-->Settings all necessary boxes are clean. Thanks for help - mauri1
