How to Install Telnet on Windows 11
You install Telnet on Windows 11 by enabling the Telnet Client optional feature.
Telnet is a fundamental network protocol and command-line tool that lets you establish a text-based terminal connection to remote computers. While it lacks the modern security of SSH, it remains useful for basic network troubleshooting.
For instance, you can use Telnet on Windows 11 to quickly check if port 23 (the default Telnet port) is open on a server. This simple test helps diagnose connectivity problems.
Once you enable this feature, you can access the Telnet client directly from the Command Prompt or PowerShell to begin connecting to remote systems.
Enable the Telnet Client feature by going to Control Panel, then Programs, and selecting “Turn Windows features on or off.” Check the box for Telnet Client and click OK. You can also use the DISM command in an administrator Command Prompt: dism /online /Enable-Feature /FeatureName:TelnetClient.
Prerequisites
Before you begin, ensure you have an active internet connection. You must also have an administrator account on your computer to modify Windows features.

Security Risks and SSH Alternative
Is Telnet safe to use on Windows 11? No. Telnet sends data in plain text, meaning anyone on your network can read your passwords. Always use SSH (Secure Shell) instead, as it encrypts your connection. Only use Telnet for local network testing.
Disabling Telnet
If you no longer need it, go back to Turn Windows features on or off, uncheck Telnet Client, and click OK to remove it.
Summary
Telnet is a legacy network tool used primarily for testing connections. You can enable it through the Windows Control Panel, or by using the dism command in an administrator Command Prompt. Always remember that Telnet is insecure; use SSH for any sensitive tasks to protect your data.
Why can’t I find Telnet in 🪟 Windows 11?
Telnet is not enabled by default in Windows 11 because it is a legacy feature. You must manually enable it through the Windows Features menu or via the command line to use it. It is hidden to prevent users from accidentally using an insecure connection method.
What is the difference between Telnet and SSH?
The main difference is security. Telnet transmits all data, including login credentials, in plain text, making it vulnerable to interception. SSH encrypts the entire connection, ensuring that your data remains private and secure. SSH is the modern standard for remote administration and should be preferred over Telnet.
