Let CCleaner "clean" away. It's original name was "Cr*p Cleaner" because that's what it gets rid of - all the junk left over from daily use. I guess they got so popular that they "cleaned" up their image!
It doesn't touch any documents or programs. It is very thorough and will get rid of any cookies you haven't excluded from it. I keep several cookies excluded from the cleaning such as Gameboomers so I don't have to log in again. Just click on Options and then Cookies... move the ones you want to keep over to the right side. If you want to do that before you click on Clean, you will have to start over.
Fireplace, yarn, knitting needles, books, wine... check. Yup, I'm ready for winter.
