Order in which command prompt executes files with the same name (a.bat vs a.cmd vs a.exe)

Okay, I did some quick experimentation based on some other searches I had going.

The gist is that the order of the commands is dependent on the order the extensions are stored in the PATHEXT environment variable. So initially I had:

PATHEXT=.COM;.EXE;.BAT;.CMD;.VBS;.VBE;.JS;.JSE;.WSF;.WSH;.RB;.RBW

and for the example above the order in which it would run it was:

something.exe
something.bat
something.cmd

Changing the order which they were defined in the PATHEXT environment variable did indeed change the order in which they were executed.
