+short_description: Modifies environment variables on windows guests
+description:
+    - Uses .net Environment to set or remove environment variables.
+    - Can set at User, Machine or Process level.
+    - Note that usual rules apply, so existing environments will not change until new processes are started.
+options:
+  state:
+    description:
+      - present to ensure environment variable is set, or absent to ensure it is removed
+    required: false
+    default: present
+    choices:
+      - present
+      - absent
+  name:
+    description:
+      - The name of the environment variable
+    required: true
+    default: no default
+  value:
+    description: 
+      - The value to store in the environment variable. Can be omitted for state=absent
+    required: false
+    default: no default
+  level:
+    description: 
+      - The level at which to set the environment variable.
+      - Use 'machine' to set for all users.
+      - Use 'user' to set for the current user that ansible is connected as.
+      - Use 'process' to set for the current process.  Probably not that useful.
+    required: true
+    default: no default
+    choices:
+      - machine
+      - process
+      - user
