Ran CCleaner and then ran another registry cleaner which came up with 18 items to be removed - why didn't the CCleaner remove these 18 items?
can you please tell us what reg cleaner are you talking about???
I'm surprised there were only 18 new finds. It's usual to find that registry cleaners use different parameters to decide what registry elements are redundant, and what aren't. CC has a reputation for being a rather cautious reg cleaner, some others are more astringent. One is not necessarily better than another.
