By default, Windows 7 comes with Telnet disabled. To install the Telnet client by using a command line, please see the following steps:

  • Open a command prompt window. Click Start, type ‘cmd’ in the Start Search box, and then press Enter
  • Type the following command: pkgmgr /iu:”TelnetClient”
  • If the User Account Control dialog box appears, confirm that the action it displays is what you want, and then click Continue
  • When the command prompt appears again, the installation is complete
