After the installation, you will see a shortcut of program, please double click it.
Program has two main tabs, Cleaner and Registry.
Cleaner is the main feature of the program, which will allow you to optimize your system, by removing unused and temporary files. It also protects your personal privacy by removing traces of the websites you have visited and the files you have opened.
Registry a more advanced feature which analysis your computers registry (where windows system settings are stored) and fixes any problems and inconsistencies that exist.
In tools section, you can uninstall programs or clear the list of programs.
Cleaner Settings are the list of checkboxes next to the navigation buttons and are present when you are in the Cleaner mode.
By checking and unchecking options you can choose to include or exclude items from the cleaning process. For example, if you uncheck the Cookies option then no Internet Explorer cookies will be removed. (You also have the choice to keep specific cookies in the Options section.)
To actually run the cleaner and remove the files, it's a simple case of just clicking the Run Cleaner button.
To use Registry cleaner, go to Registry tab and press the "Scan for Issues" button and once completed press the "Fix Selected Issues" button. You will be prompted to backup and helped throughout the process.
