HI there David, thank you for reading my blog. Unfortunately whilst hosting multiple nodes on windows is great unfortunately they crash after 1 hour or so, Some people get around this by creating macros to always start up the masternodes every 10 minutes. If you want to host multiple I recommend Ubuntu right now. I have spoken to Rolihlala the developer and he will resolve the issues with windows. Once it is solved I will make another blog on how to host multiple masternodes.
