Easily solve the telnet command failure failure under win7

telnet command Telnet is a text-based program that you can use to connect to other computers over the Internet. It gives you access to programs and services on remote computers. Then if you open the Windows NT's own CMD input telnet command, the system prompts me that "not internal or external commands are not runnable programs or batches", how to solve it?

My One feeling is that the CMD function has failed, so I tried the ping command again. The strange thing is that the ping function can be used normally.

At this time, I thought that this feature may not be enabled on telnet on windows7.

Then open the "Control Panel", find the program and function, and then click the "open or close windows function" in the upper left, and the windows function dialog box will pop up. There are many windows in this dialog box. Small function, then find the Telent Client, check it, confirm it!
