I think he is doing this:

define service{
        use                             server-1-hour-retry-emailonly-noticket
        hostgroup_name                  windows
        service_description             cpu
        check_command                   check_nrpe_win_cpu!80!90
        }

define service{
        use                             server-servicehours
        hostgroup_name                  windows
        service_description             commit charge
        check_command                   check_nrpe_win_memory_page!90%!95%
        }

define service{
        use                             server
        hostgroup_name                  windows
        service_description             uptime
        servicegroups                   uptime
        check_command                   check_nrpe_win_uptime!1h
        retry_check_interval            70
        }

So, all hosts in the windows host_group will get the uptime,cpu, and
commit charge services.
