Telnet startup in the win7 Command line window
Telnet is a common remote login and administration tool used by system administrators and is integrated into the system as a standard system component for users in Windows 2000/xp/2003/vista systems. However, by default, the Telnet service is prohibited, and typically we simply run services.msc to open service management, find the Telnet service item to set its startup type to "Manual" or "Automatic," and then start the service to use. However, in Windows 7, you cannot find and enable the Telnet service by using the above method. So how do you get back the Telnet feature of Windows 7?
1. Hide the reason

In fact, not having Telnet in the service Manager is not Windows 7 discarding telnet, but Windows 7 does not have the Telnet service installed by default. This is the first time Microsoft has removed Telnet from the system default component from a personal system, similar to Windows Server 2008. I think Microsoft should do this for security reasons, after all, Telnet data is transmitted in clear text, attackers and easy access to sensitive information through sniffing. Based on security considerations, it is recommended that you use a more secure, encrypted SSH remote management approach.

2. Install Telnet

Telnet is also very handy as a personal user. Installing Telnet under Windows 7 and Windows Server 2008 is slightly different, and you can do this by using the following procedure. Click "Start" → "Control Panel" → "Program", "in the program and function" to find and click on "Turn on or off Windows features" into the Windows Feature Settings dialog box. Locate and tick the Telnet client and Telnet server, and finally "OK" for a moment to complete the installation. In addition, we can install "TFTP client", "Internet information Service" and so on through the wizard.

When the installation is complete, the Telnet service is disabled by default. You also need to perform "start" → "Run" and enter Servcies.msc to open the service Manager. Locate and double-click the Telnet service entry to set it to start as manual (more secure, only enabled when needed), and finally "start" the service "OK" to exit.

Open the control Panel, select Turn Windows features on or off under program, and then tick the Telnet client in the pop-up dialog box.
When you are on the hook, be careful not to tick the Telnet server.
The use of Telnet commands under Win7 is also somewhat special.
First have to enter telnet under the cmd into Telnet mode, in Telnet mode can enter several commands,
