Muse-IO functions as a stand alone app, which streams Muse(2014) data over the network in OSC format. Muse Monitor's streaming mode functions in the exact same way, streaming OSC data over the network, the only difference being, usually one would run Muse-IO on the same machine, streaming data to the local loopback IP 127.0.0.1, where as Muse Monitor is run on your phone and requires your computers real LAN IP to stream to.
In my (very biased ) opinion, using Muse Monitor is far easier than Muse-IO. To use Muse-IO, you need to pair your Muse with Windows (not easy in itself), then navigate to the correct folder in the dos command line and manually run some very specific commands.. Where as with Muse Monitor, your run the app and press the stream button
The only other solution if you want to access your data on a 2016 Muse in Windows, would be to install Visual Studio, learn C#.Net and build your own app with their Windows developer SDK. If you're interested in doing that, you can find the API documentation here. There is also a very basic sample app included.
