Telnet client in Windows Vista and 7

Recently I had a need for telnet client, and when tried to access the one that comes with Windows, I was surprised it was missing. At first I thought it was removed from Windows 7, but later found out it was only disabled since Vista came out.

To re-enable it go to Start > Control Panel > Programs and Features > Turn Windows features on or off. Tick Telnet Client and click on OK.
