How to Install Telnet on Windows 11
Windows 11 lets you install the Telnet client by turning on an optional feature. This installs the Telnet client, a simple tool for connecting to other computers using text commands.
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.
Telnet is an older tool that lets you send text commands over a network. While it’s not as secure as modern methods, it can still be useful for checking network connections. Many devices still use it for basic management. It’s disabled by default on Windows 11 because it’s not secure for general use.
Telnet itself is a basic network language that lets you open a text-only connection to a remote computer. It’s not as secure as newer methods like SSH, but it’s handy for checking basic network issues.
For example, you can use the Telnet client in Windows 11 to quickly see if port 23 is open on a server. This helps figure out why you can’t connect to it.
You can use the ‘telnet’ command in Command Prompt or PowerShell to connect to a specific IP address and port. For example, typing `telnet example.com 80` will try to connect to the web server at example.com on port 80. If you see a blank screen or a connection message, the port is likely open. If it says ‘connection refused’ or times out, the port might be closed or blocked.
Once you turn on this feature, you can open Telnet right from the Command Prompt (cmd) or PowerShell. Both command-line tools work the same way for installing and running Telnet.
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.

- Search for PowerShell in the Start Menu.
- Right-click it and select Run as administrator.
- Run this command:
Install-WindowsFeature -name Telnet-ClientVerify Installation
To check if Telnet is installed, open Command Prompt and type telnet. If it works, you will see a blank screen or a help menu. If you get an error, the installation did not complete.
Security Risks and SSH Alternative
Is Telnet safe to use on Windows 11? No. Telnet sends data, including your login details, in plain text. This means someone watching your network traffic could easily steal your passwords. For secure connections, especially over the internet or untrusted networks, you should always use SSH (Secure Shell). SSH encrypts your connection, making it safe. Only use Telnet for simple tests on a trusted local network where security is not a concern, and never for logging into sensitive systems.
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.
Telnet is not enabled by default in Windows 11 because it is an insecure legacy feature. Microsoft hides it to prevent accidental use, as it poses security risks. You must manually enable it through 'Turn Windows features on or off' or via the command line if you need to use it for specific network testing purposes.
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.
While Telnet is primarily used for basic network connectivity checks (like verifying if a specific port is open), SSH is a versatile tool for secure remote access, file transfers (using SFTP or SCP), and tunneling network traffic. If you need to log into a server or manage network devices remotely, SSH is the standard and secure choice. Telnet is only suitable for very basic, non-sensitive diagnostic tasks on a local network.
