If you don't have the Kodak software anymore, you can remove the button utility from your PC. To do this, open your application folder, search for the one that you want to remove and drag its icon to the Trash. To make sure that you don't have any leftover files in your system, it is advised to go to the Library/Preferences location, and to /Library/Application Support/ in order to search for the developer's name or the application name. If you find any of them, just drag it to the Trash. To complete the process, empty the trash.
