short_description: Add, change, or remove registry keys and values
description:
    - Add, modify or remove registry keys and values.
    - More information about the windows registry from Wikipedia (https://en.wikipedia.org/wiki/Windows_Registry).
options:
  path:
    description:
      - Name of registry path.
      - 'Should be in one of the following registry hives: HKCC, HKCR, HKCU, HKLM, HKU.'
    required: true
    aliases: [ key ]
  name:
    description:
      - Name of registry entry in C(path).
      - This is an entry in the above C(key) parameter.
      - If not provided, or empty we use the default name '(default)'.
    aliases: [ entry ]
  data:
    description:
      - Value of the registry entry C(name) in C(path).
      - Binary data should be expressed a yaml byte array or as comma separated hex values.  An easy way to generate this is to run C(regedit.exe) and
        use the I(Export) option to save the registry values to a file.  In the exported file binary values will look like C(hex:be,ef,be,ef).
        The C(hex:) prefix is optional.
  type:
    description:
      - Registry value data type.
    choices:
      - binary
      - dword
      - expandstring
      - multistring
      - string
      - qword
    default: string
    aliases: [ datatype ]
  state:
    description:
      - State of registry entry.
    choices:
      - present
      - absent
    default: present
notes:
- Check-mode C(-C/--check) and diff output C(-D/--diff) are supported, so that you can test every change against the active configuration before
  applying changes.
- Beware that some registry hives (C(HKEY_USERS) in particular) do not allow to create new registry paths.
