What Is Telnet and Why Is It Disabled by Default?

Telnet is a network protocol used to communicate with remote servers over port 23. Microsoft disables it out of the box because:

  • Telnet transmits data in plain unencrypted text, making it vulnerable to packet sniffing.

  • Modern secure network management relies primarily on SSH (Secure Shell) protocols.

  • Disabling unused network clients reduces the overall attack surface of Windows 10.

  • However, Telnet remains an indispensable tool for testing open TCP ports (telnet <hostname> <port>).
