The Norton Utilities releases are collections of software utilities.
Peter Norton published the first version for DOS, The Norton Utilities, Release 1, ca 1981. Release 2 came out several years later, subsequent to the first hard drives for the IBM PC line. Peter Norton's company was sold to Symantec in 1990. However his name remains as a "brand" for Symantec's range of utility and security software for home users.
This version 6.0 supported all DOS 5.0 features including "task switching" which was an early form of multitasking made popular by operating systems like the Amiga and later, Windows.
