+module: win_security_policy
+version_added: '2.4'
+short_description: changes local security policy settings
+description:
+- Allows you to set the local security policies that are configured by
+  SecEdit.exe.
+notes:
+- This module uses the SecEdit.exe tool to configure the values, more details
+  of the areas and keys that can be configured can be found here
+  U(https://msdn.microsoft.com/en-us/library/bb742512.aspx).
+- If you are in a domain environment these policies may be set by a GPO policy,
+  this module can temporarily change these values but the GPO will override
+  it if the value differs.
+- You can also run C(SecEdit.exe /export /cfg C:\temp\output.ini) to view the
+  current policies set on your system.
+options:
+  section:
+    description:
+    - The ini section the key exists in.
+    - If the section does not exist then the module will return an error.
+    - Example sections to use are 'Account Policies', 'Local Policies',
+      'Event Log', 'Restricted Groups', 'System Services', 'Registry' and
+      'File System'
+    required: yes
+  key:
+    description:
+    - The ini key of the section or policy name to modify.
+    - The module will return an error if this key is invalid.
+    required: yes
+  value:
+    description:
+    - The value for the ini key or policy name.
+    - If the key takes in a boolean value then 0 = False and 1 = True.
+    required: yes
