Use Windows’ built-in uninstall utility which can be found on your Control Panel from the Start Menu. In Windows XP, you will see an icon named “Add/Remove Programs”. In Windows Vista and Windows 7, the same functionality is behind an icon called “Programs and Features“.
Double-click on this icon where you will see the list of each and every application installed on your computer system. Find the entry for Optimizer Pro and click on it in order to select it. By doing so, an “Uninstall” button will appear and clicking on it will start the Optimizer Pro Uninstallation procedure.
