The AMD Clean Uninstall Utility will attempt to remove any previously installed AMD Catalyst display and audio drivers, and cleans up left-over files and registry entries from the system. This helps to prepare the system for a better driver installation experience.
NOTE: The AMD Clean Uninstall Utility should only be used if the normal uninstallation procedure using the Windows Control Panel's Programs and Features option is unsuccessful.
NOTE: All previous versions of AMD display and audio drivers as well as AMD software components will be removed by the AMD Clean Uninstall Utility. This utility removes the enumerations created under the display and audio registry keys resulting from multiple graphics cards.
