I know that MinimServer 2 can access the music files and send the data over my local network, but to what? I need software on my PC to pull the music data off the network (a UPnP 'renderer' if I understand the documentation) and redirect the audio data to my DAC1 via the USB. I do not want any DSP, not even volume. I tried to research UPnP and ended up wrapped around the axle with external IP addresses, port mapping, etc., which I suspect I don't need anyway. I presume that MinimWatch (or an equivalent Android app) will communicate with MinimServer 2 to browse the library and request the music I want to hear (tracks or playlists), but what software do I need on my Win10 PC to accept the data and redirect it (unmolested) to my DAC via the USB port? I would greatly appreciate any advice, or suggestions you may have to offer.

It's not clear from the above if you want to run a Windows media player or if you want to control a Windows UPNP media renderer from a tablet/phone.

Simoncn has provided some information for the latter. I would add Tunebrowser to his list. This can run as UPNP and OpenHome.
This Wiki page provides more information on both although not necessarily upto date.
