Telnet is not present in Windows vista and later windows version by default. We need to manually select the feature from Control Panel > Turn Windows Features on or off. T

There is, however, another way to install the telnet client on these operating systems, that is, by command line. The command line can be used to automate the process in multiple machines.

Type the following command in command prompt to install the Telnet client:

dism /online /Enable-Feature /FeatureName:TelnetClient 

 

Hope it helps!
