I must say I am a little bit confused. CCleaner always cleaned my browser history of Chrome and Opera. In the last weeks it did not or I felt it did not. Now it does, no matter /AUTO or /AUTOS . Ccleaner can be seen in the taskmanager and It lasts a little bit, but then it is done. Maybe at my tests I was to quick trying whether it is done or not. I think the real reason is that I upgraded from Win 7 to Win 10. The PC is now quicker up, but not finished when I start the browser. So sorry for my eagerness.
