Norton Utilities is a utility software suite designed to help analyze, configure, optimize and maintain a computer. The current version of Norton Utilities is Norton Utilities 16 for Windows XP/Vista/7/8 was released October 26, 2012.

Peter Norton published the first version for DOS, The Norton Utilities, Release 1, in 1982. Release 2 came out about a year 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. Peter Norton himself has no connection to the brand or company.

Norton Utilities for DOS and Windows 3.1[edit]

v1.0[edit]

The initial 1982 release supported DOS 1.x and featured the UNERASE utility. This allowed files to be undeleted by restoring the first letter of the directory entry (a feature of the FAT file system used in MS-DOS, albeit one that was not originally documented). The UNERASE utility was what launched NU on its path to success. Quoting Peter Norton, "Why did The Norton Utilities become such popular software? Well, industry wisdom has it that software becomes standard either by providing superior capabilities or by solving problems that were previously unsolvable. In 1982, when I sat down at my PC to write Unerase, I was solving a common problem to which there was no readily available solution."[1]

14 programs were included, on three floppy disks, list price $80:[2][3]

  • UnErase, recovers erased files
  • FileFix, repairs damaged files
  • DiskLook, complete floppy disk displays and maps
  • SecMod, easy changes to floppy disks
  • FileHide, interactive hidden file control
  • BatHide, automatic hidden file control
  • TimeMark, displays date, time, elapsed time
  • ScrAtr, sets DOS to work in any colors
  • Reverse, work in black on white
  • Clear, clears the screen for clarity
  • FileSort, keeps floppy disk files by date or name
  • DiskOpt, speeds floppy disk access
  • Beep, causes the PC speaker to beep
  • Print, prints files

v2.0[edit]

The main feature of this version supporting DOS 2.x was FILEFIND, used for searching for files.[citation needed] This 1983 release added hard disk support, and the PRINT program was renamed LPRINT to avoid conflict with the DOS command introduced in MS-DOS 2.0 as PRINT.COM.[4] Following this release Norton became Utilities Editor of PC Magazine.[5]

v3.0[edit]

This version, released in 1984, included Directory Sort, Disk Test, File Attributes, File Find, File Size, Line Print, List Directories, System Information, Text Search, Volume Label, Wipe Disk and Wipe File.

v3.1[edit]

This 1986 version added the Quick UnErase (QU) and Unremove Directory (UD) programs.

v4.0[edit]

Norton Utilities 4.0 for DOS

Release 4.0 (1987, list $99.95) added four new programs:[6]

  • Ask, used for batch file programming
  • File Info, add descriptions up to 65 characters long to each file
  • Norton Change Directory, displays a graphic directory tree; change, remove, rename or make directories
  • Norton Integrator, a menu system to tie the utilities together. Previously the utilities were accessed by typing the command name (usually a cryptic 2 character name such as FF) at the DOS prompt.

v4.0 Advanced Edition[edit]

This version (list $150), released simultaneously with 4.0 standard edition, added Speed Disk, a disk defragmenter, and Format Recover.

v4.5 Advanced Edition[edit]

Norton Integrator from Norton Utilities 4.5 for DOS

Norton Disk Doctor was the major addition in this 1988 release.[7] It also includes Wipedisk, Wipefile, Batch Enhancer and a sector level disk editor, a system information diagnostic utility, and a disk caching program (NCACHE), which was between 10 - 50% faster than Microsoft's SMARTDrive when properly configured.

v5.0[edit]

Release 5.0 included more features, including a utility to perform low level formatting on hard disks, and changes such as password protection on the more "dangerous" utilities. It also included a licensed version of the 4DOS replacement for COMMAND.COM called NDOS. This version also allowed the choice of "classic" names (such as FF.EXE) or longer names (such as FINDFAST.EXE); these were configurable in the updated version of the Norton Integrator menu system.

v6.0[edit]

Norton Utilities 6.0 for DOS

Norton Utilities 6.0 supports DOS 5 and Windows 3.1. It includes Windows Program Manager support, but the tools are still DOS-based, so a set of icons were supplied.

It includes Norton Disk Doctor, Disk Editor, Disk Tools, Speed Disk, Norton Cache, Disk Monitor, Diskreet, NDisk, System Information, NDOS.[8]

The speed of Speed Disk was faster than previous release.

Diskreet supports Data Encryption Standard.

System Information now includes more detailed information on installed system.

UnErase takes advantage of DOS 5.0's Delete Tracking and Mirror File features to recover data.[9] However, MS-DOS 5.0 added a new UNDELETE.exe program, licensed from Norton competitor Central Point Software,[10] which took advantage of the same Delete Sentry control and Deletion-tracking files. (The DOS ERASE command is the same as the DEL (Delete) command.) Windows 95's Recycle Bin soon further reduced the value of UnErase.

v7.0[edit]

It supports MS-DOS 6.0, DoubleSpace, Stacker, and SuperStor disk compression tools.

It includes Norton Disk Doctor, Disk Editor, Undelete, SmartCan, NDOS, System Information, File Find, Norton Change Directory.[11]

Speed Disk remained as well, although SPEEDISK.exe was licensed by Microsoft and incorporated into MS-DOS as DEFRAG.exe in MS-DOS 6 onward.[12]

Release 7.0 had revised user interfaces for the utilities that feature a menu-driven user interface. Also some of these tools now did not need to run in full-screen-mode but just displayed a window in the center of the screen, like the disk formatter or the disk duplicator utility.

Disk Editor now includes Advanced Recovery Mode.

v8.0 for DOS/Windows 3.x[edit]

Release 8.0 was nearly the same as 7.0, but added Windows 3.1 utilities.

DOS Utilities include Norton Disk Doctor, System Information, Change Directory, FileFind, Diskreet, DUPDISK, File Fix, NDOS, Batch Enhancer, Norton Integrator, Speed Disk.[13]

Windows utilities include Norton Disk Doctor, Speed Disk, System Watch, File Compare, INI Tracker, INI Tuner, INI editor, INI Advisor

Norton Utilities for Windows 95 and later[edit]

v1.0 for Windows 95[edit]

The original Windows 95 version was released on August 1995.

As a native Windows 95 tool, it supports VFAT file system used by Windows 95.

Disk tools included with this release are not compatible with FAT32.

The Windows version of 'Speed Disk' works with much greater speed than Microsoft's supplied defrag program, as it moved groups of clusters, not single clusters as Microsoft's Windows Disk Defragmenter. Changes in the way Windows operates meant that many of the old utilities were either dropped completely or replaced with GUI based versions. However, with the advent of Windows XP onwards, Norton's 'Speed Disk' reverted to single-cluster defragmentation.[citation needed]

It was announced on 1996-10-07.[17]

It includes Norton Disk Doctor, Norton Speed Disk, Norton System Information, Norton System Doctor, Norton Protection/UnErase, Live Update.

Norton Disk Doctor, Speed Disk support FAT16 and NTFS file systems.

v3.0 for Windows 95[edit]

It was announced on 1997-11-10.[24]

It includes Norton WinDoctor, Norton Web Services, LiveUpdate Pro, Norton CrashGuard 3.0, Norton Zip Rescue, Norton System Doctor, Norton SpeedStart, Norton Optimization Wizard, Speed Disk.

PC Advisor criticised Norton Utilities 14 for delivering "little that you can't already do with Windows," although it did acknowledge that it brought two things to the table: "The registry tools, which are useful, and the performance monitor, which is interesting but not always useful".[38]

Historical[edit]

Reviews[edit]

December 18, 2009 Darian Graham-Smith of PC Pro gave Norton Utilities 14 an overall rating of 2 of 6 stars. He concluded "There's simply no good reason to pay this much for such a flimsy collection of tools."[58]

January 4, 2011 PC World Magazine reviewed Norton Utilities 15 and concluded "Norton Utilities may have outlived its usefulness. If your system isn't running as fast as you think it should, uninstalling unnecessary software and pruning background applications using Windows' own tools or downloadable freebies are a more cost-effective first defense."[59]

August 28, 2012 PC Magazine gave Norton Utilities 15 a score 3 of 5 stars. They said "This PC tune-up utility can give an aged PC a new lease on life, but its lacks some of the features and performance found in competing software."[60]

August 31, 2012 ITProPortal.com gave Norton Utilities a rating of 6 out of 10. they concluded " Norton Utilities did a satisfactory job of de-gunking and increasing the overall performance of our test laptop, but it doesn’t stack up well against rival suite System Mechanic 11."[61]

January 13, 2014 TopTenReviews.com gave Norton Utilities a 7.7 star rating out of 10 and said "Norton Utilities has good help and support features and is above average in terms of ease of use." [62]

Controversies[edit]

2012 January source code hack[edit]

On January 17, 2012, Symantec admitted to their network getting hacked. A hacker known as "Yama Tough" obtained Symantec's source code by hacking an Indian Government server. Yama Tough has released parts of the source code, and has threatened to release more. According to Chris Paden, a Symantec spokesman, the source code that was taken was from enterprise products that were between 5 and 6 years old.[63]

2012 September source code hack[edit]

On September 25, 2012 an affiliate of the hacker group Anonymous published source code from Norton Utilities. Symantec has responded that this is from the same code leaked in January, 2012. They have confirmed that the leak included source code for 2006 versions of Norton Utilities, pcAnywhere, and Norton Antivirus.[64]
