Windows 10, high load from WUDFHost.exe Windows Driver Foundation - User-mode Driver

I had posted a ton of details on here yesterday and now it is deleted. Why? That took a lot of time and research to help you all out and hopefully fix the problem? I found that the CPU being eaten up was due to the driver calling a directx 11 DLL as well as provided the numbered list requested. Did I violate some kind of TOS?

Nothing is getting deleted. Like many, many but many forums, posts with attachments are moderated. The number of spam/porn/fake medicine messages that don't invade your inbox because of this measure is relatively high.

So why was it removed? It wasn't spam, it was all technical detail on this problem.

Thanks for clearing it up, I had thought I did something wrong, and only want to help.

This issue makes using the dock for Skype meetings or Webex impossible. I have to log into my VDI through my windows Phone and Continuum dock to join any meetings that have presentations or undock my laptop.

I have been fighting with my workstation for several weeks with resource issues. Locking up, running out of memory, cpu running way with resources, fan that sounds like a jet engine, etc...

After a lot of research I stumbled upon this post as I was looking at Windows processes and Endpoint protection as the cause of the issues. However I have now unplugged my dock, uninstalled the current DisplayLink driver issued on December 18 and rebooted my machine. On reboot I inserted the dock USB into a different port and let it install the driver through Windows. I am happy to report that my machine has returned back to normal...so far...

Running Windows 10 Anniversary. After letting windows install the driver the display adapter appears as "USB3.0 Dual Video Dock" Driver Provider: DisplayLink Driver Date: 8/17/2016 Driver Version: 8.0.762.0 Along with the display adapter I have "USB Giga-Ethernet" Driver Provider: DisplayLink Driver Date: 5/20/2016 Driver Version: 8.0.403.0

Fingers are crossed but it appears to have solved my issue!

Hello,

Would you please be able to share your CPU+GPU details?
Also what kind of resolution are you external displays?
If I can understand the CPU issue, I don't get the high memory usage...



As a general update, I have created support tickets with details from the different posters here in preparation to share a development build to test. However, during tests, an unrelated issue was found so I have not yet shared anything as I am not satisfied with the quality.


Kind regards,
Alban

Nice to see you are having some success. I just went through the steps you outlined here, and my problem persists. Just moving the mouse on the screen causes WUDFHost to still jump from 4-25% CPU.

It took a while for windows to recognize the display adapters, but my keyboard and mouse it had no issue with.
