Having done some more playing around with various units, something I notice is that older hardware (e.g. 3rd-gen Intel Core systems/P67 and older chipsets) tend to show some quirks with power management and such. It's nothing terrible but Win7 was the last OS that really supported those 100%. Of course, those are End Of Life now so it's not surprising. The two 6th gen Intel systems I have both work flawlessly with 10.
