Multiple profiles is not very difficult, it's not widely used but it fairly easy.
Each user have their own profiles, but you can have more than one and select at boot time which profile to load. In the device manager you can control each device and what profile they work under, the same thing with services. In that way the machine while running the SDR software is running with the minimum of devices and services. That makes faster and sometimes more reliable. So you have a profile in which all the networking services, anti-virus, firewall, etc are turned off. Have you ever gone to a library and found the floppy drives doesn't work? They did not disconnect them, they disabled them for the "public" profile, if the librarian login as themselves, then floppy drive works fine. Sometime on TeamSpeak if we are both running Windows I can walk you through making a couple of changes so you can see how to do it yourself.
