Putty - https://www.chiark.greenend.org.uk/~sgtatham/putty/latest.html

Launch Putty, put the IP address of your node and make sure SSH is select and the proper port.  Normally 22 or 8022.  Its normally a good idea to not use 22.  

Don't forget to save your session after you fill in the IP address so you can reuse the profile.

If your getting old (like me) I need a bigger font.  Click on Appearance and change to 14.  don't forget to go back to session and save.
