    r"""
    Edit the parameters of a task. Triggers and Actions cannot be edited yet.

    Args:

        name (str):
            The name of the task. This will be displayed in the task scheduler.

        location (str):
            A string value representing the location in which to create the
            task. Default is ``\`` which is the root for the task scheduler
            (``C:\Windows\System32\tasks``).

        user_name (str):
            The user account under which to run the task. To specify the
            'System' account, use 'System'. The password will be ignored.

        password (str):
            The password to use for authentication. This should set the task to
            run whether the user is logged in or not, but is currently not
            working.

            .. note::

                The combination of user_name and password determine how the
                task runs. For example, if a username is passed without at
                password the task will only run when the user is logged in. If a
                password is passed as well the task will run whether the user is
                logged on or not. If you pass 'System' as the username the task
                will run as the system account (the password parameter is
                ignored).

        description (str):
            A string representing the text that will be displayed in the
            description field in the task scheduler.

            Boolean value that indicates whether the task is restarted when the
            computer cycles into an idle condition more than once.

        ac_only (bool):
            Boolean value that indicates that the Task Scheduler will launch the

        delete_after (bool, str):
            The amount of time that the Task Scheduler will wait before deleting
            the task after it expires. Requires a trigger with an expiration
            date. Valid values are:

                - False (to disable)

def add_action(name=None, location="\\", action_type="Execute", **kwargs):
    r"""
    Add an action to a task.

    Args:

        name (str):
            The name of the task to which to add the action.

        location (str):
            A string value representing the location of the task. Default is
            ``\`` which is the root for the task scheduler
            (``C:\Windows\System32\tasks``).

        action_type (str):
            The type of action to add. There are three action types. Each one
            requires its own set of Keyword Arguments (kwargs). Valid values
            are:

                - Execute
                - Email
                - Message

    Required arguments for each action_type:

    **Execute**

        Execute a command or an executable

            cmd (str):
                (required) The command or executable to run.

            arguments (str):
                (optional) Arguments to be passed to the command or executable.
                To launch a script the first command will need to be the
                interpreter for the script. For example, to run a vbscript you
                would pass ``cscript.exe`` in the ``cmd`` parameter and pass the
                script in the ``arguments`` parameter as follows:

                    - ``cmd='cscript.exe' arguments='c:\scripts\myscript.vbs'``

                Batch files do not need an interpreter and may be passed to the
                cmd parameter directly.

            start_in (str):
                (optional) The current working directory for the command.

    **Email**

        Send and email. Requires ``server``, ``from``, and ``to`` or ``cc``.

            from (str): The sender

            reply_to (str): Who to reply to

            to (str): The recipient

            cc (str): The CC recipient

            bcc (str): The BCC recipient

            subject (str): The subject of the email

            body (str): The Message Body of the email

            server (str): The server used to send the email

            attachments (list):
                A list of attachments. These will be the paths to the files to
                attach. ie: ``attachments="['C:\attachment1.txt',
                'C:\attachment2.txt']"``

    **Message**

        Display a dialog box. The task must be set to "Run only when user is
        logged on" in order for the dialog box to display. Both parameters are
        required.

            title (str):
                The dialog box title.

            message (str):
                The dialog box message body

    Returns:
        dict: A dictionary containing the task configuration

    *Event*

        The trigger will be fired by an event.

            subscription (str):
                An event definition in xml format that fires the trigger. The
                easiest way to get this would is to create an event in Windows
                Task Scheduler and then copy the xml text.

    *Once*

        No special parameters required.

    *Daily*

        The task will run daily.

            days_interval (int):
                The interval between days in the schedule. An interval of 1
                produces a daily schedule. An interval of 2 produces an
                every-other day schedule. If no interval is specified, 1 is
                used. Valid entries are 1 - 999.

    *Weekly*

        The task will run weekly.

            weeks_interval (int):
                The interval between weeks in the schedule. An interval of 1
                produces a weekly schedule. An interval of 2 produces an
                every-other week schedule. If no interval is specified, 1 is
                used. Valid entries are 1 - 52.

            days_of_week (list):
                Sets the days of the week on which the task runs. Should be a

                the names of the days of the week.

    *Monthly*

        The task will run monthly.

            months_of_year (list):
                Sets the months of the year during which the task runs. Should
                be a list. ie: ``['January','July']``. Valid entries are the

                Sets the days of the month during which the task runs. Should be
                a list. ie: ``[1, 15, 'Last']``. Options are all days of the
                month 1 - 31 and the word 'Last' to indicate the last day of the
                month.

            last_day_of_month (bool):
                Boolean value that indicates that the task runs on the last day
                of the month regardless of the actual date of that day.

                .. note::

                    You can set the task to run on the last day of the month by
                    either including the word 'Last' in the list of days, or
                    setting the parameter 'last_day_of_month' equal to ``True``.

    *MonthlyDay*

        The task will run monthly on the specified day.

            months_of_year (list):
                Sets the months of the year during which the task runs. Should
                be a list. ie: ``['January','July']``. Valid entries are the
                full names of all the months.

            weeks_of_month (list):
                Sets the weeks of the month during which the task runs. Should
                be a list. ie: ``['First','Third']``. Valid options are:

                    - Second
                    - Third
                    - Fourth

            last_week_of_month (bool):
                Boolean value that indicates that the task runs on the last week
                of the month.

            days_of_week (list):
                Sets the days of the week during which the task runs. Should be
                a list. ie: ``['Monday','Wednesday','Friday']``.  Valid entries
                are the names of the days of the week.

    *OnIdle*

        No special parameters required.

    *OnTaskCreation*

        No special parameters required.

    *OnBoot*

        The task will be triggered by a session change.

            session_user_name (str):
                Sets the user for the Terminal Server session. When a session
                state change is detected for this user, a task is started. To
                detect session status change for any user, do not pass this
                parameter.

            state_change (str):
                Sets the kind of Terminal Server session change that would
                trigger a task launch. Valid options are:

                    - ConsoleConnect: When you connect to a user session (switch
                      users)

                      (switch users)
                    - RemoteConnect: When a user connects via Remote Desktop
                    - RemoteDisconnect: When a user disconnects via Remote
                      Desktop
                    - SessionLock: When the workstation is locked
                    - SessionUnlock: When the workstation is unlocked

    Returns:
