A new window will pop up with a list of features. Scroll down until you find “Telnet Client“.
Put a checkmark next to “Telnet Client“.
Click “OK” at the bottom of the window.

Windows might take a few seconds to install Telnet. Once it’s done, you’ll be good to go!

Method 2: Using Command Prompt/PowerShell

This method uses commands to enable Telnet. It’s a bit more technical, but if you’re comfortable with using Command Prompt or PowerShell, here’s how:

Using Command Prompt:

Search for “Command Prompt” in the Windows search bar.
Right-click on “Command Prompt” and select “Run as administrator” (important!).
In the Command Prompt window, type the following command and press Enter:
dism /online /Enable-Feature /FeatureName:TelnetClient

Using PowerShell:

Search for “PowerShell” in the Windows search bar.
Right-click on “PowerShell” and select “Run as administrator” (important!).
In the PowerShell window, type the following command and press Enter:
Install-WindowsFeature TelnetClient

Both commands will enable Telnet. You might see a progress bar indicating the installation.

Method 3: Using third-party tools for enabling Telnet

While the built-in methods for enabling Telnet on Windows 10 and 11 are straightforward, some users prefer third-party tools for added flexibility or additional features. Here are a few third-party options you can explore: PuTTY, Tera Term, SecureCRT and MobaXterm.

Security Risks: Third-party tools can be a security risk, especially when dealing with something as sensitive as remote access. There’s a chance they might contain malware or introduce vulnerabilities.
Unnecessary: The built-in methods (Control Panel and Command Prompt/PowerShell) are generally safe and effective for enabling Telnet on Windows 10/11.
Focus on Official Methods: This guide focuses on providing users with safe and reliable ways to enable Telnet through official Windows features.

We can address the need for alternative methods by mentioning this in the existing “Why Enable Telnet? (Optional)” section: By focusing on the official methods and highlighting the security risks, we can provide a more secure and user-friendly guide.

While these methods are the most recommended way to enable Telnet, it’s important to remember that Telnet transmits data without encryption. This means information sent through Telnet could be intercepted by others on the network. It’s generally recommended to use more secure methods like SSH whenever possible.

Testing Telnet Connection

Once you’ve enabled Telnet, you can test it to see if it’s working. Here’s a basic example:

Open Command Prompt:
- Press Win + R, type cmd, and hit Enter.
- Alternatively, search for “Command Prompt” in the Start menu.
Telnet to a Remote Host:
- In the Command Prompt, type:
- telnet <hostname> <port>
- Replace with the actual hostname or IP address of the remote server you want to connect to. Replace with the specific port number (usually 23 for Telnet).
Check the Connection:
- If the connection is successful, you’ll see a blank screen with a cursor.
- If it fails, you’ll receive an error message indicating the reason (e.g., “Could not open connection to the host”).
Exit Telnet:
- To exit Telnet, press Ctrl + ], followed by typing quit and hitting Enter.
- Remember to replace and with the relevant details. Happy testing! 🚀🔍

Security Considerations (Important)

Telnet, while a functional tool for remote access, has a major drawback: it lacks encryption. This means any data sent through a Telnet connection, including usernames, passwords, and commands, can be easily intercepted by someone snooping on the network. This poses a significant security risk, especially on public or unsecured networks.

Plaintext Transmission:

Telnet sends data in plaintext, which means that any information (including usernames, passwords, and commands) is visible to anyone monitoring the network.
Attackers can easily intercept and read sensitive data exchanged during Telnet sessions.
Mitigation: Whenever possible, use secure alternatives like SSH (Secure Shell) that encrypt the communication.

Lack of Authentication and Encryption:

Telnet lacks robust authentication mechanisms. It typically relies on simple username/password pairs.
There is no built-in encryption for Telnet traffic.
Mitigation: If you must use Telnet, consider implementing additional security layers, such as IP filtering or VPNs.

Vulnerabilities and Exploits:

Telnet has known vulnerabilities, including buffer overflows and remote code execution.
Attackers can exploit these weaknesses to compromise systems.
Mitigation: Keep your Telnet client and server up to date. Disable Telnet when not needed.

Default Ports and Banner Grabbing:

Telnet usually operates on port 23 by default.
Attackers can perform banner grabbing (reading the initial server response) to identify Telnet services.
Mitigation: Change the default port or use port knocking techniques to obscure Telnet services.

Brute-Force Attacks:

Since Telnet lacks strong authentication, it is susceptible to brute-force attacks.
Attackers can repeatedly guess usernames and passwords.
Mitigation: Implement account lockout policies and use strong, unique passwords.

Logging and Auditing:

Telnet sessions are often not well-logged.
Lack of proper auditing makes it challenging to trace unauthorized access.
Mitigation: Enable detailed logging and regularly review logs for suspicious activity.

Telnet Sniffing:

Attackers can use packet sniffers to capture Telnet traffic.
This allows them to extract sensitive information.
Mitigation: Use encryption (e.g., SSH) to protect data in transit.

Legacy Systems and Services:

Some legacy systems still rely on Telnet for management.
These systems may not support modern security features.
Mitigation: If possible, migrate away from Telnet to more secure protocols.

Remember that while Telnet has its uses, it should be used cautiously and only when necessary. Whenever possible, opt for more secure alternatives to protect your data and systems.
