DON'T use msconfig OR CCleaner to stop start up programs.
Download CodeStuffStarter
or Mike Lin's StartUp Control Panel to control auto starts. CodeStuffStarter will show programs AND services running on boot. They can be disabled using that program. Mike Lin's program is also very simple to use and startups can also be disabled using that program.
msconfig should only be used for trouble shooting. Personally, have never used CCleaner to control start ups.
