I am creating a service using CreateService. The service will run again fine if it happens to crash and I would like to have Windows restart the service if it crashes. I know it

    Used Deltanine's approach, but modified it a bit to be able to control each failure action:

    SERVICE_FAILURE_ACTIONS servFailActions;
    SC_ACTION failActions[3];
    
    failActions[0].Type = SC_ACTION_RESTART; //Failure action: Restart Service
    failActions[0].Delay = 120000; //number of seconds to wait before performing failure action, in milliseconds = 2minutes
    failActions[1].Type = SC_ACTION_RESTART;
    failActions[1].Delay = 120000;
    failActions[2].Type = SC_ACTION_NONE;
    failActions[2].Delay = 120000;
    
    servFailActions.dwResetPeriod = 86400; // Reset Failures Counter, in Seconds = 1day
    servFailActions.lpCommand = NULL; //Command to perform due to service failure, not used
    servFailActions.lpRebootMsg = NULL; //Message during rebooting computer due to service failure, not used
    servFailActions.cActions = 3; // Number of failure action to manage
    servFailActions.lpsaActions = failActions;
    
    ChangeServiceConfig2(sc_service, SERVICE_CONFIG_FAILURE_ACTIONS, &servFailActions); //Apply above settings
