And also my lowest dpc latency went from 400 to 200.
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.

2019-09-05T15:04:25+00:00 I deleted the update file and when I opened my laptop everything was not laggy, but then it started to lag again, dpc latency going back up when I move my mouse. And also ive realized that my laptop works completely fine when its on safe mode, but I cant do everything in safe mode. And for some reason my background is now constantly black, and i'm not in safe mode.

Press Windows key + R
Type: appwiz.cpl
Hit Enter
Click View installed updates
Select the recent update KB4512941
Right click it then click uninstall.
Restart then check if stability/functionality is restored. If it is, proceed with the next steps.
The update will try to install again, so use the following to block it:
Is there an option or work around to block updates or hardware drivers that might cause problems?
Yes, Microsoft has released a KB update (KB3073930) that will let users block or hide Windows or driver updates.
You can download it at the following link:
https://support.microsoft.com/en-us/kb/3073930
After downloading, launch it, click Next, wait while it detects pending Windows Updates.
Click the Hide Updates menu.
Scroll through the list then select then select the update. Check the box next to the update then click Next to confirm changes.

I recommend you attempt a repair upgrade instead:
Download the Media Creation Tool Now

Right click the MediaCreationTool.exe file then click Run as administrator.

Select the option Upgrade this PC now if you want to upgrade right away,
Click Next

Wait while Windows 10 setup does one final check to ensure your system is ready.
Windows 10 setup will check if you have enough disk space.
Please note, you have the option of choosing what you would like to keep, which includes personal files, apps and settings.
If you want to perform a new install or just keep your files click Change what to keep. Once you have chosen the desired options, click Install to begin.
This will be your screen for a little while. During the installation, your computer will restart several times.
After the first restart, Windows 10 setup will resume. You will notice the setup experience has once again been refined from the previous animated circle. This will be your screen for a while. When complete, Windows 10 setup will restart automatically.
Sign into your account.
Wait while Windows 10 completes application updates and post setup tasks.
That’s it, the Windows 10 Feature Update is installed.You can check Windows Update for latest updates, click Start > Settings > Update & security > Windows Update > Check for Updates.
How to prepare your computer before upgrading?
Although updating to Windows 10 version 1903 is a relatively simple process, similar to a repair upgrade; users should perform some basic pre-requisites before initiating the upgrade.
