should fix following when setting windows path in ansible.cfg:
{"ansible_facts": {}, "changed": false, "failed_modules": {"setup": {"changed": false, "failed": true, "msg": "Get-AnsibleParam: Parameter 'fact_path' has an invalid path '/home/myname/ansible/test/C:\\users\\vagrant\\facts.d\\' specified."}}, "msg": "The following modules failed to execute: setup\n"}
