IOW, Musehub is always able to communicate with someone unknown out there on the Internet. I see little or no discussion of this issue - maybe I'm missing it? Is this something that will be changed in the future? This seems to me to be highly user-unfriendly and potentially dangerous.' I don't see anything to assure me that it ISN'T. 'I don't know if Muse Hub Service is communicating with anywhere on the internet while its running with all those options turned off, but it seems to me to be quite likely that it CAN if it wants, and I as the computer owner have no control over it. I can find no way to change this behavior. That means that even if you stop the service, it will automatically start again after a re-boot. That option is greyed out, even if you are logged on as Administrator. What you cannot do is change the Service Type to anything from its default, Automatic. You can turn off its Auto Update options. 'Something else I though I'd mention about Muse Hub: you can turn off its 'Community Acceleration' option.

I'll quote an earlier post of mine about Musehub:
