The majority of computer users out there have heard about the registry but they have no clue what it does or how they can use it. The registry keeps track of all sorts of information on the programs and operating system. Most of this information is necessary for things to run smoothly. However, the registry also contains information that is useless, no longer necessary and can even harm your computer. While Windows has no built-in way for a user to get to the heart of issues with the registry, programs out there like Reg Organizer help them do just that.
