With so many scam registry tools out there, no wonder so many look for a true freeware program to solve their Windows Registry woes. But are there really problems that build up in the registry that need fixing? Are registry cleaners the solution to most of my computer issues? What does a registry cleaner actually do? The short answer is no, there are few real "registry problems" that a registry cleaner/repair/fix-it tool can actually solve. So why are there so many of these programs?! They do have a purpose, but few actually have anything to do with the registry anymore. Confused? Understandable. Here are some much more thorough answers to some of the more frequent questions we get about these ubiquitous tools: What Does a Registry Cleaner Do?How Often Should I Run a Registry Cleaner?What Types of Computer Problems Do Registry Cleaners Fix?Should I Fix All the Problems a Registry Cleaner Finds?Will a Registry Cleaner Speed Up My Computer?Will a Registry Cleaner I Pay for Fix More Problems Than a Free One?Why is CCleaner Asking me to Pay?
