Help needed, simple instructions to start monitoring agentless windows

I have a redhat icingaweb2 server, monitoring solaris and redhat servers using nagios plugins (ssh_check).
its using the default icinga (local / non AD) user and i have added ssh keys to all linux/solaris servers so icinga can ssh straight in with root privs to run nagios checks.
Now i need to start monitoring our windows servers. i need to do it agentless. does someone have an easy set up guide ? including user config ?
current config has been set up by editing config files under /etc/icinga2/conf.d (hosts files, ssh check files etc). I have lots of experience supporting and configuring unix servers, but not much windows experience.
