     - The filter option filters only the first level subkey below ansible_facts.
     - If the target host is Windows, you will not currently have the ability to use
       C(filter) as this is provided by a simpler implementation of the module.
-    - If the target host is Windows you can now use C(fact_path). Make sure that this path
-      exists on the target host. Files in this path MUST be PowerShell scripts (``*.ps1``) and
-      their output must be formattable in JSON (Ansible will take care of this). Test the

-      This option was added in Ansible 2.1.
     - This module is also supported for Windows targets.
     - This module should be run with elevated privileges on BSD systems to gather facts like ansible_product_version.
