    Install a DISM capability

    Args:
        name (str): The capability to install
        source (str): The optional source of the capability
        limit_access (bool): Prevent DISM from contacting Windows Update for
            online images
        image (Optional[str]): The path to the root directory of an offline
            Windows image. If `None` is passed, the running operating system is
            targeted. Default is None.
        restart (Optional[bool]): Reboot the machine if required by the install

    Example:
        Run ``dism.available_capabilities`` to get a list of available
        capabilities. This will help you get the proper name to use.
