After you install the “Dial-up Networking” to connect to the internet, there will be the small window shown as the figure below. This will inform you that the “Dial-up icon” will be minimized itseft and placed on the “Taskbar” at the bottom of the desktop and it will be alert everytime when you connect to the internet successfully.

If you don’t want it to be shown again, you check at “Do not show this dialog box in the future.” And then click close.
