Computer system including local computer with capability to automatically update operating system or application program from network server

摘要

A local computer stores a current program such as an operating system or an application. A network server stores a latest program which is a latest version of the current program, and an identifier program for generating an identification corresponding to the latest program upon interrogation. An updater program is alternatively stored on the local computer or the network server for causing the latest program to be transferred from the network server to the local computer and replace the current computer program. The current program and the latest program each include a startup program configured to interrogate the identifier program, determine if the identification corresponds to the current program, and if the identification does not correspond to the current program, run the updater program.
