+        The provisioner '%{name}' doesn't support provisioning on
+        Windows guests via WinRM. This is likely not a limitation
+        of the provisioner itself but rather that Vagrant doesn't know
+        how to run this provisioner over WinRM.
+
+        If you'd like this provisioner to work over WinRM, please
+        take a look at the Vagrant source code linked below and try
+        to contribute back support. Thank you!
