It has become apparent that some people are landing on a post I made about WeTransfer looking for a download link to grab a copy of PuTTY. Ever eager to please, the link below is where you would download PuTTy for your system, whatever particular flavour of system that may be!
It is completely free to download PuTTy.
An alternative to using PuTTy at all, is to get yourself onto a free and Open-Source Linux distro, like Ubuntu, or Mint. Then you can just open up the terminal right there, in your OS. Your web server runs on Linux, because its a pretty speedy and cool lightweight way to get computing done. So the machine sitting in front of you can too.
/end of Linux rant.
