Is there a Windows exe that does nothing?

Problem

Is there a "noop"-esque exe somewhere as part of the Windows installation? I'm preparing some batch jobs and scheduled tasks, and for a couple reasons I'd like to reference an executable that does nothing -- i.e. launches with no visible window, and quits immediately. Does such an executable exist in the usual Windows installation anywhere? or how can I come close? I do not want to have to depend on anything not already included in Windows.
