The third tab shows you what happens and what has been done. The second tab lets you select any settings before executing them. Cleaner uses the same familiar three tab interface with the first tab, which shows you the main choices, including Crap cleaner Filehippo, registry, tools, and options. The first panel is called Windows, which is used to clean unnecessary system files, and the second panel focuses on removing the remains from the third party software. The Cleaner section is divided further into two panels. The Options area covers the application settings and all the other three perform different tasks in different areas of the machine.
