As mentioned before this is likely the most recent how-to: https://www.hagensieker.com/wordpress/2018/07/17/op25-for-dummies/ https://www.hagensieker.com/wordpress/2018/07/17/op25-for-dummies/ A year ago I wrote this, when it was just starting to be a thing to install OP25 on a Raspberry Pi: http://kb9mwr.blogspot.com/2017/07/listening-to-local-700-mhz-simulcast.html http://kb9mwr.blogspot.com/2017/07/listening-to-local-700-mhz-simulcast.html While I don't have any desire to run op25 on Windows, unfortunately I can see a good how-to on that sort of thing being desirable to many. I am a ham and I like to tinker, not just be a end user. So I don't see anyone using this on Windows really contributing anything back to the community. I really urge people to dig into things deeper than skin level, you never know, you just might learn something. But that is just me.
