I've upgraded many machines, mostly laptops thus far from 7 pro to 10 pro. Biggest issue is Service Host: Local System (19) in task manager hogs the CPU making the machine almost worthless.

Countless times I have to end this task. In doing so the system says I have to click an abandon data checkbox and click shut down. The machine never shuts down, but once I do this the system performance is back to normal. It seems the systems work just fine without Service Host: Local System (19). Is there any fix to this? This is the November build.
