    In Windows XP, start-run-cmd.exe takes me to a command line interface, just like command.com does. command.com seems older... What's the difference between the two?

    The cmd.exe is Windows 32-bit command interpreter. Command.com is a 16-bit equivalent of MS-DOS embedded in Windows. If you look at the task manager when you have command.com open you'll likely see an ntvdm.exe program running -- that is NT/2000 kernels "virtual dos machine". You cannot run 32 bit applications from a command.com window.
