Slow or lagging system performance is the most common problem faced by Windows 10 users. And when this happens, the first thing we do is check the CPU usage via Task Manager. While doing so, if you find that it is nearing 100% due to a file named WUDFHost.exe, what will you do?
Don’t have an answer? Worry not many Windows users have reported facing the problem due to WUDFHost.exe; hence we are here with the solution.
Here, in this post, we will discuss how to fix CPU hogging caused by the WUDFHost process.
What is WUDFHost.exe?
WUDFHost stands for Windows User-mode Driver Framework Host, and it is a legitimate Windows system process, important for the operating system. However, if you see it consuming more than 80% CPU power and wants to kill it, it is not recommended. Doing so might disrupt the system’s functioning.
However, if this process is slowing down the system and restricting the functioning, this post is for you. We will help fix the WUDFHost problem.
7 Ways to Troubleshoot wudfhost.exe High CPU usage Windows 10
Here we will enlist 7 workable solutions to fix excessive CPU Usage caused by WUDFHost.exe. Just work your way down and find the right solution for you that helps get rid of the Windows User-mode Driver Framework Host problem.
Fix 1: Scan system for malware infections
WUDFHost.exe is a genuine Windows process, and it is safe to use, however sometimes treacherous malware or viruses hide as WUDFHost process. Therefore, to determine if the WUDFHost.exe running is genuine or not, we should know the file location.
A genuine WUDFHost.exe file is in the C:\Windows\System32 folder; however, if you find that the file running is saved at some other location, it can be a threat.
Tip: To check the file location, open Task Manager by pressing Ctrl+Shift+Esc. Look for WUDFHost.exe process > right-click > open file location. Here you can see the path where the file is saved.
In such a case, scanning the system for malware infections is a must. For this, we suggest using the System Protector module offered by Advanced System Optimizer.
You must be thinking, why use a module when you can use a dedicated antivirus tool, right?
If a dedicated antivirus software only scans the system for infections, the best system optimizer, and a cleanup tool like Advanced System Optimizer will perform different operations.
Using this cleaning utility, you can scan the system for junk files, update drivers, fix registry errors, and do a lot more.
To use System Protector, follow the steps below:
1. Download, install and launch Advanced System Optimizer.
2. Click Security & Privacy > System Protector
3. To perform the scan, click Start Scan. For thoroughly scanning the Windows system, we suggest performing Deep Scan.
4. Once the scan is completed, fix all the errors, and restart the system.
Now check if the WUDFHost.exe process is still running or not.
If the problem persists, move to the next fix.
Fix 2: Update outdated & corrupt device, drivers
If the WUDFHost.exe process is genuine, then the High CPU Usage could result from a corrupted or outdated driver. To fix this, updating device drivers is recommended. You can do it the traditional way via Device Manager or can do it automatically via Driver Updater.
Note: If you update drivers manually, you need to gather information like version number, the bit of operation system, device driver model number, and other details. If you want to save yourself from all this, try updating drivers automatically.
Driver Updater, the module offered by Advanced System Optimizer, is an automatic, simple, and effective way to update drives. To use it for updating drivers, you don’t need to collect any system information; all you need to do is follow the steps below:
1) Download, install and run Advanced System Optimizer
2) Click Regular Maintenance > Driver Updater
3) Click Start Scan Now to begin the scanning process.
4) Once the scan is done, update all the outdated drivers.
(to update all drivers at once, you need the Pro version of Advanced System Optimizer).
5) Restart the system to save changes.
6) Now check the CPU usage percentage; it should have come down. If that’s the case, congratulations, the WUDFHost.exe hogging issue is fixed. If not, read further.
