Introduction: Telnet, a widely-used protocol for remote computer access, can be a valuable tool for troubleshooting and network management. While Windows 10 has Telnet disabled by default due to security concerns, it can easily be enabled with a few simple steps. In this comprehensive guide, we’ll walk you through enabling Telnet on Windows 10 through the Control Panel, Command Prompt, and PowerShell.

Enabling Telnet through Control Panel:

1. Open the Control Panel by typing “Control Panel” in the Start Menu search bar.
2. Click on “Programs” and then select “Turn Windows features on or off.”
3. Scroll down to find “Telnet Client” and check the box next to it.
4. Click “OK” to initiate the installation.
5. Wait for the installation to complete and click “Close.”

Enabling Telnet through Command Prompt:

1. Open the Command Prompt by typing “cmd” in the search bar.
2. Type “telnet” and press Enter. If Telnet is not installed, follow the prompts to install it.
3. Once installed, type “telnet” again and press Enter.
4. Type “o” to open a connection, then enter the IP address or hostname of the remote computer.
5. Provide the username and password when prompted to log in.

Checking if Telnet is enabled: To verify if Telnet is enabled, access the command line interface of the network device.

• For Cisco devices, use “show running-config” to check for ‘line vty’ configuration.
• For Juniper devices, use “show configuration | display set” to check for ‘services telnet’ configuration.
• To check the connected sessions, use “show users” for Cisco and “show system users” for Juniper.

Why Telnet may not work in Windows 10: Telnet is not enabled by default in Windows 10 due to security reasons. While it can be activated, it is recommended to use more secure protocols such as SSH or SFTP. If Telnet is being used, a Virtual Private Network (VPN) is advised for additional security.

Installing and Uninstalling Telnet via PowerShell: Telnet can be installed and uninstalled using PowerShell. For installation, use “Install-WindowsFeature Telnet-Client,” and for uninstallation, use “Uninstall-WindowsFeature Telnet-Client.”

Conclusion: Enabling Telnet on Windows 10 can enhance your ability to troubleshoot and manage network devices. However, it’s crucial to prioritize security and consider alternative, more secure protocols for remote access. By following the provided steps, users can easily enable Telnet and explore its functionalities.
