System Host Process

As a last resort, I decided to check the System Host Process tree again because I felt this is where the problem exists. I noticed Windows Update was listed as a running service.

Modifying what gets synced can reduce the impact of the CPU fan remaining constant. Another process I notice triggers the CPU fan is IAStorDataSvc.
