Description:

def set_computer_policy(name,
                        setting,
                        cumulative_rights_assignments=True,
                        adml_language='en-US'):
    '''
    Set a single computer policy

    Args:
        name (str):
            The name of the policy to configure

        setting (str):
            The setting to configure the named policy with

        cumulative_rights_assignments (bool): Determine how user rights
            assignment policies are configured. If True, user right assignment
            specifications are simply added to the existing policy. If False,
            only the users specified will get the right (any existing will have
            the right revoked)

        adml_language (str): The language files to use for looking up
            Administrative Template policy data (i.e. how the policy is
            displayed in the GUI).  Defaults to 'en-US' (U.S. English).

    Returns:
        bool: True if successful, otherwise False

    CLI Example:

    .. code-block:: bash

        salt '*' lgpo.set_computer_policy LockoutDuration 1440
    '''
    pol = {}
    pol[name] = setting
