That's imho not the normal message in a command prompt if a command
is not found. (I would have expected something like
"xetex is not recognized as an internal or external command").

Are you using the normal standard cmd.exe as prompt? 

What happens if you issue e.g. "set" in this prompt?

That's normal. That happens if you doubleclick an application
without gui.
