Easily solve the telnet command failure under win7

telnet command Telnet is a text-based program that can be used to connect to other computers over the Internet. It gives you access to programs and services on remote computers. If you open it after Windows7 comes CMD input telnet command, the system has prompted me "is not an internal or external command is not operable program or batch", how to solve it?

my first impression The CMD function is invalid, so I tried the ping command again. The strange thing is that the ping function can be used normally.

this time I think probably the telnet this feature has not been turned on Windows7.

then open the "Control Panel", find Programs and Features, then click the top left "open or close the windows function" dialog box will pop up windows function, this dialog box, there are many small features of Windows, Then find TelentClIEnt, check it and confirm it!
