Telnet is a simple text-based network protocol that is used for administrators to access remote computers over TCP/IP networks like the Internet. Telnet was first created and launched in 1969. With the launch of Windows Vista, Microsoft has removed the default Telnet services. However, it still can be added in Windows 7, Windows 8, Windows Server 2008, Windows Server 2008 R2, Windows Server 2012 and Windows Vista.

There are two methods to adding telnet client / server tools.

First Method – Command Prompt

1. Open the Command Prompt with administrative privilege (To do this go to C:\Windows\System32 and on cmd.exe right click and run as administrator, when UAC prompts then click Yes).

2. Type the following command to use Telnet Client :

pkgmgr /iu:”TelnetClient”

or the following for Telnet Server :

pkgmgr /iu:”TelnetServer”

3. Press Enter from keyboard.

To check that the Telnet is installed or not, open command prompt. Write telnet and press Enter from keyboard. It should show “Microsoft Telnet>” as below screenshot. To exit the telnet, issue quit command.
