Starting with ansible

__etc___ansible___hosts.yaml

# /etc/ansible/hosts.yaml

[local]
localhost       ansible_connection=local

[windows]
192.168.1.123

[windows:vars]
ansible_connection=winrm
ansible_winrm_scheme=http

First steps with ansible.md

For the file group_vars/windows/main.yml I suggest to use ansible vault

group_vars___windows___main.yaml

#group_vars/windows/main.yaml
desktop_username: "plain username"
desktop_password: "plain_password"

ping.yaml

---
- hosts: windows
  name: "Test ping verso macchina Windows"
  vars:
    ansible_user: "{{ desktop_username }}"
    ansible_password: "{{ desktop_password }}"
  tasks:
  - name: 'Include some additional variables'
    win_ping:
