You go to 'Start' - 'Control panel' - 'Add/Remove programs'

1) a system software runs the system where an application system runs over the system software. 2) a system software are programs that run & control the hardware units of the system & an application software doesn't. 3) system programs are written using dll, exe files for windows & rpm files for linux etc, where application software are developed on the basis these files or by using different language files. 4) u can't create applications using system software but application software are specially made to create applications for users.
