What is Windows Driver Foundation (WUDFHost.exe) process?

Windows Driver Foundation is a set of libraries and tools that reduce complexity while using drivers on your Windows PC. In other words, this process helps you continue using a stable system all the time. At times, users may face issues with the system, where the Windows Driver Foundation occupies a major chunk of the CPU usage. While it does not exactly restrict the functionalities of the CPU for most users, it certainly drains the battery and might cause system freezing at times, especially if the usage shoots up to 100%. Attempting to kill the process in the Task Manager doesn’t help because it is a system process.

To find if the strain on the CPU usage is because of Windows Driver Foundation – User-mode Driver Framework (WUDFHost.exe) or its constituent wudfsvc.dll file, open the Task Manager by right-clicking on the Taskbar and selecting Task Manager.

Here, check for the process consuming high CPU usage. Is it Windows Driver Foundation? In the Windows 11 or Windows 10 Task Manager, you may see the entry Windows Driver Foundation prefixed with any one of these:

• WUDFHost.exe, or
• User-mode Driver Framework Host process, or
• Kernel-mode Driver Framework Host process.

The WUDFHost.exe process is located at:

C:\Windows\System32

If it indeed consumes high resources, try some of these troubleshooting suggestions:

1. Run Windows Update
2. Run Troubleshooters
3. Troubleshoot in Clean Boot State
4. Try removing peripherals from the system
5. Update and re-install WiFi drivers
6. Suggestions for the Pro’s

Let’s check out these steps in detail.

1] Run Windows Update

Make sure that your Windows operating system is up to date with the latest patches and fixes. If not, it is recommended to install all the available updates.

2] Run Troubleshooters

Run System Maintenance Troubleshooter. To run the System Maintenance Troubleshooter. Open Run, type the following and hit Enter:

msdt.exe -id MaintenanceDiagnostic

Does it help?

Next, run the System Performance Troubleshooter. To do so, open an elevated Command Prompt, type the following and hit Enter to run the Performance Troubleshooter.

msdt.exe /id PerformanceDiagnostic

This troubleshooter helps the user adjust settings to improve operating system speed and performance.

3] Troubleshoot in Clean Boot State

A Clean Boot will help you troubleshoot the issue. Log on to the system as an administrator. Press Windows + R to open the Run window. Enter the command ‘msconfig’ and press Enter.

Click the General tab, and then click Selective Startup. Clear the Load Startup Items check box, and ensure that Load System Services and Use Original boot configuration are checked.

4] Try removing peripherals from the system

Remove peripherals from the system one by one and check if it resolves the issue. If it does, that particular peripheral might need to be replaced or maybe its Driver updated.

5] Update and re-install WiFi drivers

Many users have reported that reinstalling the WiFi drivers helped them resolve the issue. The process to update Device Drivers is as follows:

Press Win+X and click on Device Manager to open it. In the list, which is in alphabetical order, find ‘Network Adapters’ and click the forward-pointing arrow in front of it.

Find the wireless drivers in the list, right-click on them one by one and update them.
