CCleaner does indeed include a Registry cleaner, but the user must invoke it separately so it does not clean the registry unless you tell it to do so.

However, I have used the registry cleaner routine without problems and it not only gets rid of "orphans" in the windows registry that may be left over after program uninstalls, it also includes a "backup" option that saves a tiny file that can be used to restore it back to exactly the way it was before the cleaning, just in case. I have always chosen the option to save that file when the window prompts at the end of the registry cleaning, just in case, but have never to date had to revert due to a problem with it.

But the main "cleaner" icon at the top of the list, which opens highlighted by default, does not touch the registry. It is mostly involved with locating and removing Temporary Internet Files that your browser has cached, Cookies that you don't want piled up in long lists over time (IME Internet Explorer gets mired down in too many cookies over time and that is the single biggest reason for slow loading or even nonloading of webpages) and a few other things it does all contribute to keeping the thing running fast and well. The entire list of what the "cleaner" app does is also user selectable on the LH side such that you can customize the cleaning to not take out certain things if you so desire.

AND -- at first install ccleaner gives ou the option to KEEP any cookies from websites such as this forum where you can specify that the forum software "keep me logged in" such that you don't have to enter passwords every visit. Very nice feature.
