I upgraded my 9365 today with Win 10 KB4032188. This may or may not be related but I noticed the system was very hot about an hour after the update completed.
I check the performance and the system process was using 45% utilization while running at 2.5 GHz. The drive was showing 100% usage.
I checked the Resource Monitor and the System was writing to the file listed below at a consistent 10 MB/s and it went on for more than 25 minutes when I shut it down. I have now uninstalled McAfee because I feel there is no way such operations will not significantly shorten the life of this new unit.
