Windows XP contains a copy of the Windows ME boot disk, stripped down to bootstrap only. This is accessible only by formatting a floppy as an MS-DOS startup disk. Files like the driver for the CD-ROM support were deleted from the Windows ME bootdisk and the startup files (AUTOEXEC.BAT and CONFIG.SYS) no longer had content. This modified disk was the base for creating the MS-DOS image for Windows XP. Some of the deleted files can be recovered with an undelete tool.[25] With Windows Vista the files on the startup disk are dated 18 April 2005 but are otherwise unchanged, including the string MS-DOS Version 8 © Copyright 1981–1999 Microsoft Corp inside COMMAND.COM. However the only versions of MS-DOS currently recognized as stand-alone OSs, and supported as such by Microsoft are MS-DOS 6.0 and 6.2.2, both of which remain available for download via their MSDN, volume license, and OEM license partner websites, for customers with valid login credentials. MS-DOS is still used in embedded x86 systems due to its simple architecture and minimal memory and processor requirements. The command line interpreter of NT-based versions of Windows, CMD.EXE, maintains most of the same commands and some compatibility with DOS batch files.
