I've read a number of articles from PC World to Computer Hope extolling the necessity of using registry cleaners which carry the names as 'Registry Cleaners', EasyCleaners', 'RegistryOrganizers', 'RegCure', among other names. However, when I came across a book (McGraw Hill Osborne) entitled "The Healthy PC" by Carey Holzman, a PC Repair Specialist of 15 years, it stated (Chapter 12, p.195) that these are softwares to avoid. The reason is simply that based on his years of experiance, they create more problems than it solve. He compared it to putting a band aid to a gapping wound.
