If you are using telnet to test and troubleshoot services you will be “surprised” that telnet is not installed by default.

'telnet' is not recognized as an internal or external command,
operable program or batch file.

To to enable it back follow this procedure:

  1. Go to Start – > Control Panel -> Programs -> Turn Windows Features On and Off
  2. Check Telnet Client and click OK (See screenshot below)
  3. After a while it is ready
  4. Enjoy
