It’s very rare that I use Telnet these days, so it took a long time for me to notice that by default it was not packaged with Windows 7. More than likely this is make Windows more secure by default, as Telnet is very insecure and whenever you have the choice you should always use SSH. However, with that being said, you can quickly re-enable Telnet by following these steps:
- Control Panel
- Programs And Features
- Turn Windows features on or off
- Check Telnet Client
After that you can start Telnet via Command Prompt.
