Telnet is a network protocol that allows you to connect to remote computers and devices over a network. It is often used for testing and troubleshooting network services. Windows 11 does not have Telnet enabled by default, so you need to turn it on before using it.
Enabling Telnet on Windows 11 is a straightforward process that only takes a few minutes. Once enabled, you can use the Telnet client from the Command Prompt to connect to other machines.
This guide will walk you through each step in detail, explaining why each action is necessary. Whether you are a beginner or just need a refresher, this article will help you get started with Telnet on Windows 11.
By the end, you will also find answers to common questions and troubleshooting tips to make sure everything works smoothly.
Quick Note
Before enabling Telnet, make sure you have administrative privileges on your Windows 11 device. This is important because enabling or disabling Windows features requires admin rights.
Also, ensure your device is connected to the internet or local network where you want to use Telnet, as the tool relies on network connectivity to function.
Step 1: Open Windows Features
The first step to enable Telnet is to access the “Windows Features” panel. This panel allows you to turn Windows optional features on or off.
To do this, press the Windows key on your keyboard or click the Start menu. Then, type Turn Windows features on or off and select the matching search result.
This will open a small window listing many optional Windows features, including Telnet Client and Telnet Server.
Step 2: Enable the Telnet Client
In the “Windows Features” window, scroll down until you find Telnet Client.
By default, this feature is unchecked, meaning it is disabled. Check the box next to “Telnet Client” to enable it.
After selecting it, click OK. Windows will start installing the necessary components. This process usually takes less than a minute.
Once completed, you will see a confirmation message or the window will close automatically.
Step 3: Verify Telnet is Enabled
To confirm that Telnet is now enabled, open the Command Prompt.
You can do this by pressing Windows key + R to open the Run dialog box, then type cmd and press Enter.
In Command Prompt, type telnet and press Enter.
If Telnet is enabled, you will see a prompt that looks like this:
Welcome to Microsoft Telnet ClientIf you get an error message saying the command is not recognized, it means Telnet is not enabled correctly and you should repeat the previous steps.
Step 4: Using Telnet to Connect to a Remote Host
Once Telnet is enabled, you can use it to connect to remote servers or devices.
The basic command structure is:
telnet [hostname or IP address] [port]For example, if you want to connect to a server at IP address 192.168.1.10 on port 23 (the default Telnet port), you would type:
telnet 192.168.1.10 23Press Enter to initiate the connection.
If the connection is successful, you will see a blank screen or a login prompt, depending on the remote system.
Why Specify a Port?
Network services often run on specific ports. Telnet defaults to port 23, but some servers may use different ports for security or configuration reasons. Specifying the correct port is essential for connecting successfully.
Alternative Method: Using PowerShell to Enable Telnet
If you prefer using PowerShell instead of the graphical interface, you can enable Telnet with a single command.
Open PowerShell as Administrator by right-clicking the Start button and selecting Windows Terminal (Admin) or Windows PowerShell (Admin).
Then, type the following command and press Enter:
Install-WindowsFeature -Name Telnet-ClientIf this command does not work, you can try this alternative:
dism /online /Enable-Feature /FeatureName:TelnetClientWait for the process to complete, then check Telnet availability as described in Step 3.
Frequently Asked Questions (FAQs)
Is Telnet secure to use?
Telnet sends data, including passwords, in plain text, which means it is not secure over untrusted networks. For secure remote connections, consider using SSH (Secure Shell) instead.
Why can’t I connect to a server using Telnet?
Possible reasons include the server not having Telnet enabled, the port being blocked by a firewall, or network issues. Verify the server’s settings and your network configuration.
How do I exit the Telnet client?
To exit a Telnet session, type quit or press Ctrl + ] to open the Telnet prompt, then type quit and press Enter.
Can I use Telnet on Windows 11 Home edition?
Yes, Telnet Client is available on both Home and Pro editions of Windows 11.
What ports does Telnet use?
By default, Telnet uses port 23, but it can connect to any port specified in the command.

If you have followed all the steps and Telnet still does not work, consider the following:
- Check your Windows Update status; sometimes missing updates can affect optional features.
- Ensure your firewall or antivirus is not blocking Telnet connections.
- Restart your computer after enabling Telnet to apply changes properly.
- Visit the official Microsoft support page for more detailed troubleshooting: Microsoft Support
