A method for changing over a general-purpose OS display for an information processing apparatus to a dedicated display screen includes accessing a setup procedure describing setup processing and at least an account generating process for generating user account information for a general-purpose operating system (“OS”). The method includes accessing changeover information for changing over a general-purpose OS display screen for the information processing apparatus to a dedicated display screen, and in response to starting up the general-purpose OS for the first time, executing the setup processing including the user account generating process based on the setup procedure stored by the procedure storage unit, changing over the general-purpose OS display screen to the dedicated display screen based on the changeover information stored by the changeover information storage unit, and displaying the dedicated display screen. An apparatus and a program product perform the method.
