Registry repair programs are generally pretty simple applications. They scan your registry looking for entries that are not valid and then present the list to you. You then review the list and confirm the entries are not valid and then tell the program to either delete them or repair them. Many invalid entries are caused by programs that you uninstall. The uninstall process leaves behind registry entries that were used by the uninstalled program or it deletes a shared file that should not have been deleted. Typical invalid entries would be a non-existent program calling a specific file or making a configuration setting or an existing program calling a non-existent file that may have been deleted by another program's uninstall process. Invalid entries can cause a range of problems such as loading a program, process or service that has no reason to be loaded or not loading one that is needed. The bottom line is that each time a registry cleaner is used, it is wise to review the list of errors before allowing the cleaner to delete or repair any entries.
