If like me you prefer not to have to install a third party Telnet client into your windows 7 setup but cant figure out how to get the default client working then this is for you.
While Windows 7 does come with a default Telnet client it is not activated by default, however the process to activate the Telnet client in Windows 7 could not be more simple as follows.
> Start
> Control Panel
> Programs And Features
> Turn Windows features on or off
> Check Telnet Client
> Hit OK
After that you can start Telnet via Command Prompt.
now to use the Telnet client again is a very simple process
> start
> type telnet into the search bar
> press enter
you should now see the following screen

once you have the above screen type o<space>192.168.xxx.xxx ( the first character before the space is a o as in oscar and the ip is the ip address of your receiver obviously )
you will now be asked to input your username and password and from there you can do all the usual things a Telnet session brings but without needing a third party application such as putty.
