In general it will log a message to the eventlog and stop. Up until 
https://github.com/mhammond/pywin32/issues/1563 & 
https://github.com/mhammond/pywin32/pull/1566, it ended up reporting a 
normal `SERVICE_STOPPED` with an exit code of zero, but now it reports a 
non-zero code so you can configure it to auto-restart on exceptions.

HTH,
