What is igfxpers.exe?
The genuine igfxpers.exe file is a software component of Intel® Common User Interface by Intel Corporation.
Intel’s Display Resolution Persistence Module is part of its Common User Interface which accompanies Windows drivers for Intel graphics cards and onboard GPUs such as the Graphics Media Accelerator and its HD and Iris successors. It launches at system startup. Portables should always have it running to avoid losing resolution settings for external monitors or projectors when removed or turned off, (including docking stations), and to ensure restoring the onboard display’s native values. It can cause high CPU and RAM usage. Desktops with one monitor may allow disabling “igfxpers.exe” using "msconfig" and "startups," although Intel advises not to. It should be stopped as possible disguised malware, using the Task Manager, if it is not in “C:\Windows\System32,” if Intel or nVidia graphics hardware is not in use, or if multiple instances are running. Intel Corporation, committed to innovation, is the world’s largest, highest-valued semiconductor manufacturer, headquartered in Santa Clara, CA, USA.
