When I clean only the recent documents part (below):
It bugs the recent document window in the start bar:
So basically, after I clean the "recent documents" folder I can no longer acess it (as if it was locked by the ccleaner) unless I restart the computer.
I don't know if it's really a bug or if you really need/should restart your computer after cleaning something with ccleaner, so if I'm the one that is making a mistake please forgive me.

PS: If anything isn't clear, say it and I will try to make it more easily understandable
