Telnet is a command line tool that is designed for administering remote servers through the Command Prompt. Unlike Windows XP and Vista, Windows 7 does not come with the Telnet client installed automatically. You will need to enable it before you can start using it. See Step 1 below to learn how to do both.

Installation

  1. 1
    Open the Control Panel. By default, Telnet is not installed with Windows 7. It will need to be manually activated in order for you to use it. You can do so through the Control Panel, which can be accessed from the Start menu.
  2. 2
    Open "Programs and Features" or "Programs". The option available to you will depend on whether your Control Panel is in Icon or Category view, but they both take you to the same place.

  3. 3
    Click the "Turn Windows features on or off" link. You may be asked for the Administrator password.
  4. 4
    Find the "Telnet Client" entry. In the list of available features, you will see an entry labeled Telnet Client. You may have to scroll down to find it. Check the box next to Telnet Client, and click OK.
    • You may have to wait a minute or two for the client to be installed after selecting it.
  5. 5
    Install Telnet through the command prompt. If you'd rather do everything through the Command Prompt, you can install Telnet with a quick command. First, open the Command Prompt by typing cmd into the Run box. At the command line, type pkgmgr /iu:"TelnetClient" and press Enter. After a moment, you will be returned to the command prompt.[1]
    • Restart the command prompt to begin using Telnet.
