      Refresh the winrepo.p file of the repository (salt-run winrepo.genrepo)
  
      If ``force`` is ``True`` no checks will be made and the repository will be
      generated if ``allow_empty`` is ``True`` then the state will not return an
      error if there are 0 packages,

          This state only loads on minions that have the ``roles: salt-master``
          grain set.
