Those articles match my understanding, but it's a bit different to your previous comment (but maybe I misunderstood your previous comment). I thought you were saying that there was at least one version of Windows where .cmd would run in cmd.exe while .bat would run on COMMAND.COM. Whereas I think the actual situation is that: on Win95 .bat would run on COMMAND.COM whereas .cmd wouldn't run at all; on NT .bat and .cmd would both run on cmd.exe. As a result, if you used .cmd you could be sure that it would never run on COMMAND.COM, so you could use the new command extensions in cmd.exe without worrying about it causing a confusing error.
