The MP1-3172 fix makes TVService react on the Windows pre-shutdown event and let it stop the TVController and all TVServer plugins cleanly. Before they were killed by the Serveice manager which led to exceptions and error messages in the logs. But: Though the TVService shuts down cleanly now (seen from MP's view), Windows does not notice that the TVService has stopped and therefore now waits for 10 seconds to get a stop notification (gives an error in the System event log) and only then continues its shutdown progress. I have found no way so far how to signal Windows that the TVService has been stopped out of .NET managed code.
