Hello, I have this problem at home: In Windows 10, time sync fails. I searched a lot of things about it, tried a lot of things, but nothing helped. What I also noticed that, it's the same problem in my wife's computer and also in my mother's computer, so only thing that comes in my mind, it must be router messing it up and my ISP recently changed our router and before that, we didn't have this problem, so, I'm almost sure, it must be router, but the question - how to fix this problem?
