I have tried to enable services individually and when the system start to hang I disable the last service I enabled and it still seems to still hang. So I disable all services again and the system shutdown fine. Start the process again with the same results.
I thought it might have been one of depended services but the service I thought was the problem has no dependences
OS was newly installed a few months ago and worked fine up to a couple of weeks ago.
I seem to see this application error lots in event viewer:
