How Can I Fix Svchost.exe (imgsvc) High CPU Usage in Windows?

Hi everyone,

My Windows PC is running very slowly because Svchost.exe (imgsvc) is using a high amount of CPU. I’m not sure what’s causing it and want to fix it without affecting my system or losing data.

Has anyone experienced this before? What’s the safest way to reduce CPU usage from Svchost.exe (imgsvc) and prevent it from happening again? Step-by-step guidance would be really helpful.

Thanks!

High CPU usage by Svchost.exe (imgsvc) is usually caused by the Windows Image Acquisition (WIA) service or corrupted system files. To fix it safely, first restart the WIA service in Services. Then update Windows, scan for malware, and repair system files by running sfc /scannow and DISM /Online /Cleanup-Image /RestoreHealth in an administrator Command Prompt. You can also disable unnecessary startup apps and restart Windows Explorer if needed. This should reduce CPU usage without affecting your files.
