I like how CCleaner wipes the "history" from programs like MS Paint, but there should be an interface to add programs to this list, i.e: Windows Movie Maker.
and how would ccleaner do this?
The Interface to Add more program is there. This is called Winapp2.ini (a link to information is in my signature field)
That said to add this infomation, one would need to usderstand what it is that needs to be cleaned. . . one cannot just say I want this program cleaned. . . point at the program and (as indent indicated you seem to be thinking)expect ccleaner to know what needs cleaning.
