The Windows version of guest-set-user-password rejects argument "crypted": true with the rather useless "this feature or command is not currently supported". Improve to "'crypted' must be off on this host". QERR_UNSUPPORTED is now unused. Drop. Signed-off-by: Markus Armbruster <armbru@redhat.com> Message-ID: <20240911131206.2503035-3-armbru@redhat.com>
