Since, I had to rebuild my pc, which was the best advise, I've gotten, from my sons, I've had Windows 8.1, with Eset Smart Security 7, I, just let everything for Microsoft, be allowed, and have not had any issues, and my pc, is just running perfectly. I, would say, that those, whom, are worried, and those, that have something to hide, such as pirated software. If, you are running, great without any issues, then, just let do it's thing, and allow all of Microsoft's traffic. B)
