The number of connections is 10, and I see it proven at least once a week when someone shares out the latest video of stupid biker tricks on their Pro box, and every motorcyclist in the company is trying to download it: "Maximum number of connections has been reached" or some such message. If you're trying to use your box as a server, we want you to buy Windows Server, not Pro. :-)
