Norton Utilities is a well-known and very classic PC utilities software for DOS and Windows, developed by Peter Norton in 1982 (later sold to Symantec Corporation). It integrates disk editing, disk diagnosis and repair, system optimization, system performance testing, virus detection and removal and many other functions in one place, can help users quickly and intelligently optimize the system, so as to improve user computer performance.

First of all, I have to declare: AppNee has no interest or patience for any all-in-one type of system tools such like System Mechanic. Any similar software will come to the end of a blind alley when they develop to the end - their functions are many but not fine, miscellaneous but not pure, can do many things but none can be done best. Anyway, since our computer needs regular maintenance to keep good performance, so System Mechanic is worth a try. Maybe it's just what you like or need.

DISM (short for Deployment Imaging and Management, AKA: DISM Plus Plus), it is just in the system folder (DISM.exe), you can run the 'CMD' (as administrator) and type 'dism' to call it out... used to install, uninstall, configuration and update the features and program packages of the offline Windows (R) or Windows PE image.
