|Just to add, its not that the CCleaner's registry cleaner is particularly bad, in fact it is probably one of the safest ones. It's just that all registry cleaners are capable of getting it wrong. |
Opinions vary but most folk these days say that using registry cleaners on a regular basis does not result in any noticeable improvement in performance, so its not worth taking the risk of screwing things up. Invalid entries (which is what they remove) are mostly ignored by the system anyway.
There are odd times that they can be of value for specific issues but I don't think yours is one of them.
Always pop back and let us know the outcome - thanks
