Hi
WAMPServer puts only one thing in the registry and that is the link to the uninstall so that you can uninstall WAMPServer using the normal windows uninstall process.
In my experience ccleaner does more damage than good, and it was unnecessary to run it after a WAMPServer uninstall anyway.
The uninstall, leaves files on your disk. These files are the files you have amended OR created since the install. Its a safety mechanism so you get one last change to rescue your databases, if you forget before uninstalling.
WAMPServer should be installed "As Administrator", therefore you may need to start command window "As Administrator" and delete these remaining files from the command windows, or sign in with an administrator account and use FileManager
