Good- that behaviour of Ccleaner is quite normal.. a bit annoying tho, implying MS leaves it there in the background 'cos it's the default and well, you OUGHT to be using it... hmmm. A bit like Cortana using RAM even if you never use it, or effectively being forced to allow MS apps to use disk space whether or no you want them.

Shouldn't really be necessary to run Ccleaner daily unless you have special reason. I only run it before I update my disk image.
