cmd.exe in Windows NT 2000, 4DOS, 4OS2, 4NT, and a number of third-party solutions allow direct entry of environment variables from the command prompt.

On the Recovery Console, which is included in all Windows 2000, Windows XP and Windows Server 2003, there is a diskpart command which is significantly different from the one included in the actual operating system.

Command Prompt, also known as cmd.exe or cmd, is the default command-line interpreter for the OS/2, [1] eComStation, ArcaOS, Microsoft Windows (Windows NT family and Windows CE family), and ReactOS [2] operating systems.
However, QEMM maximum RAM is a shared 256MB XMS/256MB EMS, which is less than what DOS 7.10 and Windows 95/98 support without QEMM. MS-DOS 7.10 provides 624K free conventional memory and up to 1GB XMS/32MB EMS; assuming unaltered MS-DOS, using HIMEM.SYS and EMM386.EXE without any 3rd party utilities. Thus, QEMM is compatible with MS-DOS 7.10 ...
Memory management on the IBM family was made complex by the need to maintain backward compatibility to the original PC design [1] and real-mode DOS, while allowing computer users to take advantage of large amounts of low-cost memory and new generations of processors.
The category Windows commands deals with articles related to internal and external commands supported by members of the Windows family of operating systems including Windows 95, Windows 98, Windows 98 SE and Windows ME as well as the NT family.
None of the FreeDOS memory managers (HIMEMX.EXE, JEMM386.EXE, JEMMEX.EXE) implement the GEMMIS API and Windows fails to start when running in conjunction with JEMMxxx since Windows fails to take over the memory management role. Windows ME, Windows 98, Windows 95, Windows for Workgroups 3.1x, and Windows 3.xx, all will fail with JEMMxxx displaying:
