docs: def install(path, restart=False):
      '''
      Install a KB from a .msu file.
  
      Args:
  
          path (str):
              The full path to the msu file to install
  
          restart (bool):
              ``True`` to force a restart if required by the installation. Adds
              the ``/forcerestart`` switch to the ``wusa.exe`` command. ``False``
              will add the ``/norestart`` switch instead. Default is ``False``
  
      Returns:
          bool: ``True`` if successful, otherwise ``False``
  
      Raise:
          CommandExecutionError: If the package is already installed or an error
              is encountered
  
      CLI Example:
  
      .. code-block:: bash
  
          salt '*' wusa.install C:/temp/KB123456.msu
