I have a beautiful CD/DVD burning program, and it has been suggested to me that because I’m getting the message "Trial Period Is Expired", it’s very likely because an anti-virus program or Registry Cleaner is removing the program when it cleans. How do I list the exception in Norton’s Systemworks so it doesn’t clean the Registry thereby removing my program? I also have CC Cleaner, and can list the exception in there.
Must I ‘uncheck’ the windows registry scanner in the Systemworks?
When the Registry Cleaner is working, does it just clean, or does it correct errors?? I’m confused and would appreciate any help offered. Thanks in advance.

I’ve noticed little things and small errors popping up like invalid so and so. So, my question is, is there a good free program to clean out the Windows registry you guys can recommend for Windows XP SP2?

I need effective windows registry cleaner because my system is working slow.
