SSH login with a certificate (Windows)

One of the most convenient ways to login to a server with SSH, is with certificates. Although the principle is pretty well documented all over the internet, I still found some issues setting it up myself from my Windows laptop, hence this walk through.

I have tried to make a simple, condensed walk through. It does require that you know what SSH is and how to use PuTTY.
