What is the last version of MS-DOS?

Answer 1

The latest that existed by itself was MS-DOS 6.22. For a while, however, Windows was partially integrated with DOS, so these MS-DOS versions could be extracted. Windows 95 revision 1 identified as MS-DOS 7; Win 95 rev 2 and Win 98 were MS-DOS 7.1 (which had support for the FAT32 file system), and Windows ME had MS-DOS 8. You can extract the DOS from Win 9x (not ME) by modifying the file MSDOS.SYS, changing the line saying "bootgui=1" to "bootgui=0" and setting the config.sys SHELL statement to the command.com that came with Windows. Someone has done this and packaged it; Google "MS-DOS 7.10" and you will find it.

Also, any time you format a disk in Windows newer than ME, you get the option to make a MS-DOS startup disk. This is MS-DOS 8. By making such a disk and using the utilities from MS-DOS 6.22, you can have a working MS-DOS 8. The VER command will still report the Windows version you used.

Answer 2

The last standalone version of MS-DOS is 6.22. A slightly upgraded version, MS-DOS 7, was included with Windows 95 and 98. The last version number is MS-DOS 8, which was a crippled version included with Windows ME, 2000, XP, and Vista.

Answer 3

MS-DOS 6.22 was the last stand-alone version of MS-DOS. Some believed that MS-DOS 7.0 was the last version of MS-DOS since Windows 95 reported MS-DOS as MS-DOS 7.0. However, this was just a shell in Windows and not a stand-alone version of MS-DOS.
