PC slower not faster after CCleaner in CCleaner Posted April 13, 2013 I thought CCleaner was supposed to sort out the Startup in Tools It's the first time I see that tab LOL! Ccleaner would not do this automatically but it looks like that would do the same as using msconfig directly. Up to you which items to disable. Some will be crucial for correct functioning of your hard/software. Here's a website that can help you: http://www.pacs-portal.co.uk/startup_search.php In the end, you can do all this but not gain a lot from it. Consider re-installing Windows if you keep having troubles. Might save you time and energy.
