As a Microsoft framework, the Windows Driver Foundation develops device drivers. But it can also become a victim of its own success.
Mainly because, the associated WUDFHost.exe process can, at times, gobble up precious CPU resources, which can slow down the computer, or worse; crash the entire system. However, it isn’t a lost cause.
Because in this article, I’ll provide a set of highly effective solutions to overcome the WDF WUDFHost High CPU consumption and restore your computer to its former glory.
What is Windows Driver Foundation & the WUDFHost.exe Process?
The Windows Driver Foundation (WDF) is a collection of libraries that help users with the complex process of writing code for Windows Driver. Users can easily develop Windows drivers that execute in both kernel and user modes.
WDF simplifies the process of managing system drivers. It is an essential component for maintaining a stable system with optimal functionality, allowing you to operate your PC smoothly.
One of the integral components of WDF is the WUDFHost, an advanced process introduced in Windows Vista and has found its way to Windows 10 & Windows 11 PCs.
The WUDFHost.exe process is specially designed to provide stability and security to different peripheral devices, like MTP devices, Portable Devices, sensors, etc., that run user-mode drivers. With its complex architecture and kernel-mode drivers, the process minimizes system failures and maintains peak performance.
But after seeing WUDFHost.exe utilize so much CPU power, you might ask:
Is WUDFHost a Virus?
No, it’s not malware as long as it’s in the right directory. To verify its authenticity, you can check its location.
Here are the steps to check the WUDFHost file location:
- Press Ctrl + Shift + Esc to open the Task Manager.
- Right-click on WUDFHost.exe or Windows Driver Foundation and choose Open file location.
If it opens in C:\Windows\System32, it’s not a virus. But in case it opens in a different folder, take the necessary measures to protect your computer.
Sometime you can get a random app to show high CPU usage usage. If the usage does not die down normally, follow our guide to fix the high CPU usage.
Why is Windows Driver Foundation Using High CPU?
The Windows Driver Foundation can exhibit high CPU usage when system files get corrupted, malware attacks on WUDFHost.exe, old Windows versions & Drivers, or unsupported drivers. It is imperative to look out for these potential problems.
Here’s why Windows Driver Foundation is using high CPU:
Conflict with Third-Party Apps
Third-party applications may be engaging in activities that cause WDF to utilize high CPU. In such cases, a simple clean boot procedure can resolve the issue, and if you know which app is responsible for the problem, just uninstall it.
Problems with Windows Drivers
This issue may arise from driver-related glitches, particularly with the WiFi drivers. If you face such problems, it is necessary to either update or reinstall the driver.

Problems with Zoom Features
Certain Zoom video features might engage the WDF processes, ultimately causing an increase in CPU resource usage. In that case, modifying the Zoom app settings.will free up the CPU.
Keep in mind that malfunctioning memory can be the primary cause of high CPU usage. The most effective solution for this is to initiate the Memory Diagnostic tool to fix the issue.
Now that you know what’s making Windows Driver Foundation consume so much processing power, let’s resolve them one by one.
How to Fix Windows Driver Foundation High CPU Usage Problem?
To fix Windows Driver Foundation consuming High CPU, make sure you are using the latest Windows version with updated drivers. If the drivers are up to date, reinstall the Network adapters, run System Maintenance, SFC & DISM scans, and perform a clean boot.
Here are the methods to fix Windows Driver Foundation’s high CPU usage problem:
1. Disable the Windows Driver Foundation Service
Turning the WDF service off will stop it from using high processing power and unburden the CPU.
Follow these steps to Disable the Windows Driver Foundation Service:
- Right-click on the Windows icon and choose Run. Or press the Windows + R key.
- Write services.msc in the text field and click OK to open Services.
- Look for Windows Driver Foundation – Kernel-mode Driver Framework or Windows Driver Foundation – User-mode Driver Framework, right-click on it, and select Properties.
- Set the Startup type to Manual and click on the Stop button.
2. Reinstall the WiFi Driver & Network Adapters
If temporary bugs or glitches are responsible for the issue, reinstalling the Windows drivers will eliminate them.
Here’s how to reinstall the Wi-Fi driver & Network adapters:
- Right-click on the Windows icon or press the Window + X key and choose Device Manager.
- Extend Network adapters.
- Right-click on any one of the devices and click Uninstall device.
- Repeat this for all the devices under the Network adapter section.
Now restart your computer, and the drivers will be installed automatically.
Mac users also check their CPU usage very easily. To know how to do that, you have to check our separate article.
3. Run the System Maintenance troubleshooter
The System Maintenance Troubleshooter, as the name suggests, detects and troubleshoots maintenance problems that can lower the performance and stability of your PC.
Below is the instruction to run the System Maintenance troubleshooter:
