I would suggest putting the exe in the startup folder either in the Start menu under the startup folder or in the registry. The registry path is as follows:

HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run

That will start it when the user logs on. Then, have the application start hidden (Form.Visible = false). When it is time, make the application visible again.

    {
        public HideForm()
        {
            Opacity = 0;
            ShowInTaskbar = false;
        }

        public new void Show()
        {
            Opacity = 100;
            ShowInTaskbar = true;

            Show(this);
        }
    }
}

Have you considered converting the application to a windows service? If you did this, you could have it run in the background automatically without any need for user interaction.
