Download Network Adapter Driver for Windows® 10
Sorry to say this, but nothing has changed.
I was previously on a gigabyte z87 and couldn't get rid of this on windows 10 64bit. No problems at all on 7 64bit and 8.1 64 bit.
That motherboard came fitted with a i217v. So I said to myself, what if the motherboard is the issue? So I went to a local shop a month ago and bought a dirt cheap asrock z97 board(with a i218v), also with a different realtek audio codec this time. Gues what? I get the almost the same dpc readings on this board. While average dpc is a little lower on this cheap asrock z97, max dpc is ridiculously high and the sound goes berserk. I get the same insanely high dpc reports experienced by others posting here.
intel, if microsoft did some drastic change to the core of win 10 compared with 7 and 8.1, you should contact them and try to fix this with them if you care about your users at all.
