Windows 10: Power Management support for a WDF driver

Hi, I am using a sample WDF driver for the OSR FX2 board. After installation, I am not seeing Power Management in the device manager for that driver. I have made the registry changes as suggested on this page: https://answers.microsoft.com/en-us/surface/forum/all/power-management-tab-is-missing-from-device/0a3c563a-5ec7-4809-9609-4bc257444590I don't see it yet. How do I enable it? Thanks & Regards,Chandra

WDF in task manager

I got the same thing on my PC.

I even did a format 2 weeks ago, defender finds nothing suspicious and yet as of yesterday I have WDF Sound appearing in task manager and using more than 50% pf CPU constantly UNLESS you unplug Ethernet cable.

I renamed both files as someone suggested and it seems to be fixed, but I literally see nothing on entire google with my type of file name which is WDF Sound. It's fixed...but I kinda feel this is a dodgy fix and it still smells a bit fishy on what that
file is and no mention of it on MS and why it is happening.
