"telnet" command application in Windows 7

        I did an experiment on vmserver last night. I wanted to test the port of the virtual machine. I found that Win7 did not install the telnet command by default. I found it. Found, make a mark (some excerpt):

1, the installation: Click "Start" → "Control Panel" → "Programs", "Programs and Features" find and click the "Open or closed Windows function" enters the Windows function settings dialog. Find and check the "Telnet client" and "Telnet server", and finally "OK" to complete the installation in a few moments.

2, start the service: "Start" → "Run", type servcIEs.msc open the Service Manager. Find and double-click the Telnet service item, set its startup mode to "manual" (more secure, only enable when needed), and finally "start" the service "OK" to exit.

3, hidden reason: In fact, Windows 7 can not find Telnet not abandoned the Telnet service manager, but by default Windows 7 does not install Telnet service. This is the first time Microsoft has removed Telnet from the personal system out of the system default components, similar to Windows Server 2008. I think Microsoft should do this for security reasons. After all, Telnet data is transmitted in clear text, and attackers and easily get sensitive information through sniffing. Based on security considerations, it is recommended that you use a more secure, encrypted SSH remote management method.
