Since the upgrade to Windows 10, my memory usage is really high, first I noticed it during a download with utorrent, then I shut the program completely out, no auto-startup etc, my memory usage stabilized(I have a 4x4GB setup, out of the 16GB it was using 14 after a 4 hour session), now, when I started downloading with Steam, the same thing happened, now I have only 700MB of RAM remaining, the problem seems to be the Non-pageable RAM, I downloaded Windows Kits for developers, checked it in poolman, the cause is the netio.sys driver, some said the solution is to update a driver, but I haven't found any driver for my MSI 970 Gaming motherboard which runs with Qualcomm Atheros Killer Network driver, what could be a possible fix, I don't want to revert to 8.1 but if it's necessary, then it's possible.

Wfpn is the tag for netio.sys, checked it in cmd
Now I quit Steam, the memory leak stopped, but the nonpageable ram is not freed, so I'm stuck with 400 MB of RAM, restarting helps
