　　调用

        private void menuAutoStartOn_Click(object sender, EventArgs e)
        {
            KFSystemAutoStart auto = new KFSystemAutoStart();
            auto.SetMeAutoStart(true);

2. 托盘图标

        //双击托盘图标
        private void notifyIcon_MouseDoubleClick(object sender, MouseEventArgs e)

                notifyIcon.Visible = true;
            }
        }

 　　　　//点击最小化，显示托盘图标，隐藏任务栏图标
        private void KFSystemForm_SizeChanged(object sender, EventArgs e)
        {
            if (this.WindowState == FormWindowState.Minimized)
            {
