Service host: local system consuming more CPU

Question

Applications are facing slowness because of High CPU used by service host:local system

Answer 1

Hello

Thank you for your question and reaching out. I can understand you are having issues related to High CPU due to service host:local

1. Disable Windows Update Delivery Optimization
   Windows update uses delivery optimization to speed up processes. But this delivery optimization can be stuck in operation and cause the High CPU Usage by Service Host. In that case, turning off delivery optimization may solve the problem.
2. Also try to Disable SuperFetch service
3. Open Task Manager and right click on Service Host then chose Go to Details
   From there right click on svchost and chose Go to Services
   In this view you'll find highlighted all services under the host
   Try to guess which one is the culprit by disabling one at a time
