Preference panes are plug-ins that allow a user to set configurations for applications or preferences for the system to provide a graphical user interface. Some third-party apps may be downloaded as preference panes, for example Flash Player, or they may create preference panes the same way MySQL or Wacom drivers do.

App Cleaner & Uninstaller allows you to preview and remove all the preference panes on your Mac installed by third-party apps. You can find preference panes in the Extensions section.

But note that, when you do it the first time, it will ask your permission to allow the app access to control System Preferences. You need to click OK in order to quickly access the preference panes from App Cleaner.
