In order to enable an user to uninstall multiple device drivers that are required by a single multifunction device all at once, an uninstall system creates during installation an installer registry for the multifunction device that is different from a system registry. Data specifying the multiple related device drivers, such as a scanner driver, printer driver, and fax driver, is stored in association with each other in this installer registry, enabling the multiple device drivers to be easily identified and uninstalled together. Further, by displaying a list dialog box, the user can indicate specific device(s) for which the multiple device drivers are to be uninstalled.
