High DPC Latency caused by wdf01000.sys

Hello,

I am posting this regarding a problem that I ran across in my laptop at the beginning of august 2019, the problem is that I am getting high DPC Latency levels that are apparently caused by wdf01000.sys according to the latency checking program, latencymon.

I really want to know if there is a fix since I have browsed a wide range of sites trying to find a fix, I could not find any. And also my keyboard stopped working for some reason, if its ok I would like to find a fix for that, but I prioritize fixing the high latency over the keyboard.

Thank you for taking your time to read this.

    I have updated to the 1903 version, and that has fixed my broken keyboard, but I am still having high DPC errors, even after i have done the pre-requisites, I also noticed that the dpc spikes when i move my mouse, but when my mouse is not moving I get 400+ dpc latency, here is the windows version and the dpc latency test results:

    I am now waiting for the update, this is the information shown in the system information and windows update area, but I am awaiting the Windows 10 setup app, it is going at a slow pace, at 2% from 10 minutes, but I will keep you updated at what happens.
