Telnet is a simple but extremely popular protocol for exchanging data between two computers. It is often used for testing computer programs. The Telnet utility is included with Windows Vista and Windows 7 computers although it is not enabled by default.
If you would like to enable Telnet, follow these steps:
1. Go to Control Panel.
Alternatively, you may download the Putty SSH utility as it can also be used as Telnet client for Windows. You can download PuTTY here.
