To completely remove a program from a computer system. When a program is installed, its files are copied to the system disk, and changes are made to certain system files and folders to allow the program to work properly. Properly uninstalling a program means deleting all of the files and undoing any changes made to system files fully. An program uninstaller removes all the components which were installed; most of the software vendors ship an uninstaller with their application.
