module: win_hotfix
short_description: Install and uninstalls Windows hotfixes
description:
- Install, uninstall a Windows hotfix.
options:
  hotfix_identifier:
    description:
    - The name of the hotfix as shown in DISM, see examples for details.
    - This or C(hotfix_kb) MUST be set when C(state=absent).
    - If C(state=present) then the hotfix at C(source) will be validated
      against this value, if it does not match an error will occur.
    - You can get the identifier by running
      'Get-WindowsPackage -Online -PackagePath path-to-cab-in-msu' after
      expanding the msu file.
    type: str
  hotfix_kb:
    description:
    - The name of the KB the hotfix relates to, see examples for details.
    - This or C(hotfix_identifier) MUST be set when C(state=absent).
    - If C(state=present) then the hotfix at C(source) will be validated
      against this value, if it does not match an error will occur.
    - Because DISM uses the identifier as a key and doesn't refer to a KB in
      all cases it is recommended to use C(hotfix_identifier) instead.
    type: str
  state:
    description:
    - Whether to install or uninstall the hotfix.
    - When C(present), C(source) MUST be set.
