Telnet is a network protocol with terminal interface support, which is implemented for connecting to a remote command line interface. Through this protocol, you can gain access to another user's computer. But sometimes when making requests in the terminal, users encounter the error "Telnet is not recognized as an internal or external command, operable program, or batch file".

The error message indicates that the client is not installed. You will not be able to use the commands of this software that is not activated on the system.

Enabling Telnet Using Windows Features Utility

By default, telnet is disabled in Windows 10 for security reasons, but you can easily activate it. The easiest way to do this is to use the Windows Features utility.

  1. Open "Search" in the start menu, enter control panel in it and open the found result.

Conclusion

I hope this article helped you and you solved your problem. I want to note that Telnet is not secure, since registration data is transmitted in clear text, and anyone can intercept them using Wireshark or other software. Therefore, using SSH as an alternative would be the best choice to ensure a secure connection.

I would be grateful if you shared this information
