- Many users have reported that the Windows Driver Frameworks uses too much CPU.
- To bypass this issue, all you need to do is follow the instructions listed below.
- Learn what this process actually does for your system and what you need to do to reduce its resource usage.
- You can look at your drivers, perform a clean boot, disable problematic devices, and more.
If your system doesn’t perform as usual and you find that the Windows Driver Foundation is using too many resources, check the guidelines in this article.
The Windows Driver Frameworks (WDF), formerly known as Windows Driver Foundation, are a set of libraries that you can use to write device drivers that run on the Windows OS.
Microsoft uses three types of WDF drivers:
- The Kernel-Mode Driver Framework for standard kernel-mode device drivers
- The User-Mode Driver Framework v1 for C++ COM-based user-mode drivers
- The User-Mode Driver Framework v2 for writing KMDF-based user-mode drivers.
Why does Windows Driver Foundation high CPU usage appear on Windows 11?
If certain components of your operating system are damaged or corrupted, you might encounter higher resource usage. That is the case with Windows host process rundll32 for example.
Almost any component can cause issues, and many reported high CPU usage by audiodg.exe in Windows 11. However, that can be fixed by reinstalling the affecting application.
We wrote in-depth on how to fix high CPU usage in Windows 11 in a dedicated guide, so we strongly recommend you check it out for more in-depth solutions.
Windows Driver Frameworks cause high CPU usage
[…] The Windows Driver Foundation service is constantly using about 30% CPU. This was not happening with the previous build.
I have left the computer running for a couple hours to see if there were any cleanup processes running, but the service is still hogging CPU.
Is WUDFHost exe a virus?
No, WUDHost.exe is not a virus, it’s a legit Windows process. It’s short for Windows User-Mode Driver Framework Host.
This system process is meant to keep your system stable. It manages and hosts all the drivers installed on your Windows computer.
Users get suspicious when this process uses up too many resources, but the process itself is completely safe and for sure not a virus or malware.
It’s possible that some of the driver it hosts or their respective devices have some problems, so we suggest you look into that and make sure they’re functional and up-to date.
Do I need WUDFHost exe?
WUDFHost.exe is a vital Windows process. It makes sure that all devices connected to your system are stable and functional.
As mentioned, it works as a host for many drivers installed on your PC, for the same reason. So it’s safe to say that you do need WUDFHost.exe if you want your whole system to run smoothly.
Can I disable WUDFHost exe?
You can disable WUDFHost. exe directly from Task Manager. Like any other process, you can simply select it and then click on End task.
But just because it’s possible to do it doesn’t mean it’s recommended. As we already stated, this is an essential Windows process.
If you disable it, it’s possible that your peripherals or other connected devices will not work as they should.
So if WUDHost.exe does take up too many resources, you should get to the root of the problem, see what’s causing it and fix it.
Disabling the process may be a quick fix, but it’s definitely not recommended for optimal performance in the long run.
