How to Decrease CPU Usage by Gfxui.Exe on Windows 10
Gfxui.exe is a process that belongs to Intel GPU. Therefore, the CPU usage issue will not happen on a PC that does not have this graphics card.
It usually occurs on computers that have both Intel GPU and a dedicated graphics card, such as NVIDIA or AMD. In most cases, it is caused by a clash between the two.
At other times, however, it could be due to faults with the Intel HD Graphics drivers or possibly a virus/malware infection.
Therefore, the first thing you should consider doing is to run a full system scan with a trusted antivirus program. We recommend you use Auslogics Anti-Malware. The tool is designed to work well with any other security program you may already have. It can even detect and eliminate malicious items the latter might miss.
After scanning your system, you can then go ahead to uninstall and reinstall the Intel HD Graphics drivers. This should stop the gfxui.exe process from taking up too much of your CPU power.
