Issue: How to Fix High CPU Usage by gfxui.exe Process?

I’ve noticed that a gfxui.exe process consumes lots of system recourses. I’ve checked Task Manager for several times and found this process taking more than 70% CPU. Could you please tell me if it’s normal? I suspect that it may be slowing down my PC.

Solved Answer

For one or another reason, Windows processes can start consuming more system recourses than they are supposed to. We have found out that these days one of the problematic system processes is gfxui.exe. It is related to Intel GPUs, so naturally, computers that have other graphic cards can hardly face a high CPU usage by gfxui.exe issue. Statistically, problems related to the aforementioned process usually occur on PCs and laptops that have two graphic cards, i.e. Intel HD and NVIDIA/AMD graphics cards.

This issue might not be noticed for ages as long as the computer/laptop runs smoothly. Unfortunately, but with the gfxui.exe high CPU usage, this is hardly possible. Specialists warn that this process is a very big consumer as it may “eat” up to 100% CPU, which is why the system may become extremely sluggish, freezing, irresponsive, the boot-up process may take a long time, and so on. 

If this is happening on your system right now, you ought to open Task Manager (click Ctrl + Alt + Delete simultaneously) and check how many CPU takes each process that is currently running. If you find gfxui.exe surpassing the threshold of 50% or more, do not ignore that because it’s a clear sign that your PC needs optimization.

According to specialists, gfxui.exe error occurs due to the clash of two graphics cards that we have mentioned before. However, although this cause is the most common, this Windows process may also be triggered to absorb much CPU power due to virus/malware infection. Luckily, Windows enthusiasts have already come up with the method that helps to work around gfxui.exe draining CPU power issue.
