Enable Telnet (Vista and Windows 7)

By default, Vista doesn't include the Telnet client, which is a text-based application for communicating with remote systems. You can install it by following these steps.


  1. Open the Programs and Features Control Panel applet (Start, Control Panel, Programs and Features).
  2. Select "Turn Windows Features On or Off."
  3. Select the "Telnet Client" option and click OK.


A dialog box appears, confirming the installation of new features. After installation is complete, close the main Programs and Features Control Panel applet. The telnet command should now be available.
