Windows 10: Why is 'Microsoft Network Realtime Inspection Service' using ALL of my graphics card...

Recently found the source eating up my GPU processing, and it's a program called 'Microsoft Network Realtime Inspection Service.exe'.

microsoft network realtime inspection service puts cpu to 100%


Since today (I have installed Plex Media Server) I got my PC to peek at 100% cpu because of microsoft network realtime inspection service.
In Security Essentials (W7) there was the option in Defender to uncheck "Enable Network Inspection System".

I can not find this option in Win10. The only option I have is to disable the Realtime protection entirely.

Does anyone know how to turn of network inspection system or any other solution to this issue.

Regards,



I run Windows 10 Enterprise Insider Preview Build 10074.

I also noticed this behavior after installing Plex (running Windows 10 Pro). Turning off "Cloud-based Protection" under Windows Defender Settings seemed to greatly reduce the high CPU cost.
