It includes SSH, which is a secure version of telnet, making it ideal for establishing secure connections to remote machines.

    Make sure your PUTTY folder ends up in the directory "C:\Program Files\PuTTY\putty.exe."

  3. 3

    Open up your favourite text editor. Paste this into the body:


    @="\"C:\Program Files\PuTTY\putty.exe\" %1"

  4. 4

    Save your file as "anything.reg." Double click on it to run it. PUTTY is now your default telnet client.
