A telnet client comes with every Windows 10 version but it is initially hidden. To enable the telnet client, run this command with full Admin privileges:
PS> Enable-WindowsOptionalFeature -Online -FeatureName TelnetClient -All Path : Online : True RestartNeeded : False
Once the telnet client is installed you can use it to communicate remotely with any port of another computer. Since the new command “telnet” is a console application, make sure you run it in a true console window like powershell.exe or pwsh.exe, but not the ISE editor.
