I have Latency problem when i do a live session playing with my DAW. The assistance of my external audio interface report that:
In these results, we look for any DPC execution times above 500µs and which core this is happening on. Core 0 is the core used by the Focusrite driver and from looking at the results, I can see that highest execution time on Core 0 is 9522µs from Wdf01000.sys. Wdf01000.sys is a Microsoft driver and is a common cause of these kinds of issues and as you can see the execution is much higher than what we consider a good execution time. 
In this case, I recommend contacting Microsoft and informing them the Wdf01000.sys driver is causing this issue and they will be able to advise on the issue

Microsoft ask me to listen to HP Assistence for this driver problem.

How can i resolve this??

Thank you for posting on the HP Support Community.


As you've contacted Microsoft regarding Wdf01000.sys driver is causing this issue.
I have a few troubleshooting steps we could try to fix the issue:  

Let's perform Windows Update and HP Support Assistant:

To check for updates now, select the Start button, and then go to Settings  > Update & security  > Windows Update, and select Check for updates.

Install updates from HP Support Assistant: Go to Download HP Support Assistant to install the tool.

  1. To open HP Support Assistant, double-click the HP Support Assistant icon https://support.hp.com/doc-images/932/c05040382.jpg.
  2. Click My devices in the top menu, and then click Updates in the My PC or My notebook pane.
  3. Click Check for updates and messages to scan for new updates.
  4. Review the list of updates. Updates with a yellow information icon are recommended. Updates with a blue information icon are optional.
  5. Click the update name for a description, version number, and file size.
  6. Select the box next to any updates you want to install, and then click Download and install.

Hope this helps! Keep me posted for further assistance.
