Hi, I installed Windows 10 last week and up until now I don't have any complaints. Last night however I noticed that the access to my NAS was really slow. Other PCs in my network didn't have this problem. After investigation I noticed that the System process (PID 4) was leeching between 50 and 70 mbps from the IP address of my NAS. First I feared I might have a virus or something but this is a fresh install and all I have installed is a few apps through the store. Anybody have a clue on how to fix this? when I disconnect WiFi the proces wil shut down. When I reconnect after a few minutes it will initially work fine. Up until the point I browse to the NAS using Windows Explorer, then it will start leeching again.
