Windows Driver Foundation

If you check the Task Manager right now, you’ll find plenty of suspicious-looking processes. Most of them are OS-related and generally harmless, while others can easily cause a nervous breakdown, and WUDFHost.exe is one of them. Let’s see what this process is, why it turns your PC into a brick, and how to deal with it.

What is WUDFHost.exe?

It’s is an executable file behind Windows Driver Foundation, a host process of the driver platform runtime. Basically, the application makes sure the drivers run smoothly.

How to fix WDF issues

Since WUDFHost.exe is a system file, deleting it isn’t the best solution. Instead, you can try and stop it from eating up your CPU.

1. Update your Wi-Fi drivers

Often, WDF causes CPU overloads because of broken Wi-Fi drivers. So your first step is to reinstall them and check if the problem disappeared.

2. Disable WDF

Stop the process altogether:

  • Press Win + R, type services.msc, and hit Enter;
  • Find User-mode Driver Framework on the list;
  • Click RMB on it, choose Properties, and change Startup type into Disabled.

3. Use troubleshooting

Troubleshooters are surprisingly effective, solving problems within minutes:

  • Press Win + R, type “control panel”, and hit Enter;
  • Set Large icons in view options and click Troubleshooting, then View all;
  • Proceed to System Maintenance;
  • Go through the process and restart the PC.

Deleting WUDFHost.exe

The original WUDFHost.exe is located in the System32 folder. Thus, if you see it in C:\Windows\System32\WUDFHost.exe, there’s nothing to worry about. But if the same-named file is located in C:\Windows subdirectories, you’re probably dealing with a malicious file, disguising itself as a system application – the virus program addresses the host process.

To uninstall it, you can use specialized software or delete the file manually. The software is simpler, requiring no deep knowledge. The second option is more complicated, but sometimes it delivers a better result, so let’s take a closer look at it.

Remove WUDFHost.exe from Control Panel

You can delete the file in a classic way:

  • Go to the Control Panel;
  • In the Programs and Features section, select the application you want to delete;
  • Click RMB and select the Delete option.

If the file can’t be removed in the standard way, boot into safe mode and repeat the steps.

Remove the file and its entries from the registry

Tinkering with the system registry, it’s better to use specialized software, like CCleaner, having previously created a backup copy of the registry.

To remove WUDFHost.exe-related files and entries from the registry:

  • Press Win + R, type regedit, and press Enter;
  • To delete entries created by malicious software in the registry editor, run a search through the Edit – Find… menu (or press Ctrl + F) and locate all WDF-related elements. Delete them one at a time, pressing F3 to continue searching for entries.
