So I�ve written this off as a general Windows 10 bug that seemingly isn�t given any attention from Microsoft developers. But even after using a Windows tweaking program to disable all telemetry and other potentially privacy-compromising Windows 10 features, the problem persisted. Since it happens every 30 minutes and Windows telemetry and �keylogging� is supposed to be sent every 30 minutes too, I suspected that the telemetry data sending might be the cause. So it definitely is either a hardware company�s fault for writing bad Win10 drivers (my network adapter is from Realtek fwiw), or Microsoft�s for doing something bad with the network drivers. I installed a dual-boot Windows 8.1 partition on the same PC and don�t have that problem here at all, with the same programs used. During this second, audio stutters disruptively and video is frozen. For me, it happens every 30 minutes: ndis.sys and other processes cause extreme DPC latency (>200ms yes ms, not �s!), which causes system delays of about one second.

I re-installed Windows 10 two times, even after clean install, the problem persists. so it looks as if the only solution is to back track to windows 7?Yes, you are right, unfortunately. from what i can gather, no one cares, and no one is trying to fix it.
