Abstract

Abstract With the software distribution medium of the present invention, it is possible to execute any application program without requiring excessive storage resources, and to simply construct an execution environment specific to a user. The software distribution medium 40 is used being loaded into a medium driving unit 14 of a software execution device comprising a computer 10, a display 20, input device 30, etc., and comprises a magneto-optical disk (MO) etc. In the storage area of the software distribution medium 40, there are stored an operating system 41 controlling operations of the computer 10, one or a plurality of any application programs 42 operating upon this operating system 41, and further a software such as a boot program etc. The functions of the operating system 41 are limited to necessary and minimum ones required for execution of the application program(s) 42 commonly stored, thus waste of the storage resources such as a main memory of the computer 10 can be avoided.
