High CPU Usage from ‘Service Host: SysMain’ Should I Disable It ??
There has been persistent system slowdowns on my windows 10 PC, and after checking Task Manager. I noticed that "Service Host: SysMain" is consistently using 20-40% of my CPU, even after I boot it.
The specs on the PC :
- Windows 10 pro
- Intel core i5.
- 8gb ram.
- 1tb hdd.
is it safe to permanently disable SysMain on a system with an HDD? will it affect boot times or app performance long term? What can I do to reduce SysMain's resource usage rather than disabling it completely ?

To reduce resource usage, stop the service temporarily or set it to manual, then monitor your system's performance.
Thank you for the reply I appreciate it
Disabling SysMain on an HDD system is safe and can improve performance if you're experiencing high CPU usage.
Thank you
