It’s very unlikely a new Windows build will resolve it, unless it just changes the way power is consumed like the registry entry does.
It is related to the Intel Iris graphics chipset and the power draw off it. I have yet to see someone with an AMD chipset complain about this issue.
There are also other side effects from this. Like external monitors going blurry (what started me on this), a slight buzzing feeling on the metal casing, constant OEM panel event log errors, and more .
I personally think it’s an internal hardware issue after all my research and testing. If there was a way to fix it, the problem would have been acknowledged by now. Instead Microsoft will not acknowledge it is happening until legally required to respond. This is to prevent recalls and lost future sales (their $$$ > a few lost customers).
