Hi TFC is a good program. You don't have to use the registry cleaner in CCleaner; it has never caused me any grief however. It creates a back up before deleting. Personally I think the danger and the hipe is way over blown. It is very mild. I really don't believe in registry cleaners and they do more harm than any good, but don't stop using CCleaner because it has a option to clean the registry. CCleaner has a lot of good tools that can help if you use them properly. All these kind a programs can be misused it you don't understand how your PC works!!
Gary!
