Registry Clean Expert scans the Windows Registry and finds incorrect or obsolete information. After fixing the invalid entries, your system will run faster and error-free. The backup/restore function lets you back up your whole Windows Registry so you can use it to restore the registry to the current status in case you encounter a system failure. Also, the start-up and BHO organizer features let you manage your start-up and Internet Explorer BHO items with ease, and you can control the programs started with Windows and Internet Explorer more handily with this feature. In short, Registry Clean Expert helps you get rid of the bloat in the Windows Registry and achieve a cleaner, faster system. The product also has the Internet Explorer Guard feature to protect your Internet Explorer home page, title, and search page from browser hijacking.

Version 3.50 contains the enhanced startup organizer and BHO organizer.
