Registry Healer and System Mechanic use a more automatic approach to fixing the registry than Norton WinDoctor, but all three products basically perform the same steps. To use any of these utilities, you simply run the application and let it find the discrepancies in the registry (usually a result of the registry editor comparing entries and scanning the installed software on the system). Of the three, System Mechanic is the most powerful, although I typically use Registry Healer because it's inexpensive and works well. The applications that I've used and that I have the most experience with are Symantec's Norton WinDoctor, which is part of Norton Utilities 2002 (I usually install Norton Utilities 2002 as part of Symantec's Norton Systemworks on an XP machine), KsL Software's Registry Healer, and Iolo Technologies' System Mechanic. Before you use any registry cleaner, you'll want to back up the registry-some of these applications even perform an automatic backup for you each day. On several occasions, I've damaged a registry by trying to fix it. You do have to be careful when cleaning up the registry, however. I've used several applications to repair invalid references in the registry. The system boots very slowly and I'm aware that a registry with invalid references can cause this type of problem. If you want to fix registry issues quickly, choose Advanced PC Cleanup. It will not only help your computer to run properly but also improve its performance.

This PC cleaning tool comes with a special module for scanning and cleaning invalid registry entries.

The system registry is getting very large, and I know numerous invalid registry entries exist on my system. Advanced PC Cleanup is one of the best registry cleaners for Windows. During the past few months, I've added many programs to my Windows XP system.
