Windows7 system telnet command expiration prompt is not a solution for internal or external life

Telnet command Telnet is a text-based program that you can use to connect to other computers over the Internet. With it, you can access programs and services on a remote computer. If you open the Windows7 with the cmd input telnet command, the system prompts me, "not internal or external commands are not operational programs or batch processing", how to solve it?

My first feeling is that the CMD function failed, and then tried the ping command, strange is the ping function can be used normally.

That's when I thought it might be on the Windows7 telnet This feature is not turned on.

Then open the "Control Panel" to find programs and features, and then click on the top left "turn on or off Windows features", will pop up Windows features dialog box, this dialog box has many small Windows features, and then find Telentclient, hit the hook, confirm it!
