I am also having win10 on el7 and weird idle load of 35%. This win10 is also constantly writing to disk. Best is to disable al diagnostics services you do not use. I also noticed that el9 is smoother with win10 guests, I copied the same guest and there it is around 14%*. But if any one has an advice to get this to levels of a linux guest doing nothing, I am very anxious to hear about it. *not exactly same processors.
