How To Enable Telnet on Windows 10

Telnet is a network protocol used to virtually access a computer and to provide a two-way, collaborative, and text-based communication channel between two machines.

It follows a user command Transmission Control Protocol/Internet Protocol (TCP/IP) networking protocol for creating remote sessions. On the web, Hypertext Transfer Protocol (HTTP) and File Transfer Protocol (FTP) simply enable users to request specific files from remote computers, while, through Telnet, users can log on as regular users with the privileges they are granted to the specific applications and data on that computer.

Telnet (client) is not enabled by default on Windows 10. You can easily follow this guide to do it.
