For some unknown reason, Microsoft decided that only the “Ultimate” version of Windows Vista ships with the telnet client installed by default. It can, however, be easily installed on all the other versions as well.
- Open the Control Panel
- Select “Programs”
- Select “Turn Windows features on or off”
- Scroll through the list, select “Telnet client”
- Press OK
- Wait (for surprisingly long)
That’s it, voila, the telnet client is now installed on your Windows Vista Non-Ultimate.
