Me too, I have the same problem with my ASUS Vivobook TP410UR after update 17134 windows 10
The brightness is set to maximum level and cannot be changed. I have tried to change it via mobility center but no result.
when I checked device manager, there is a note : "Windows has stopped this device because it has reported problems. (Code 43):
Other problem is the nvidia ge force 930MX cannot attached to the display.
My graphics is Intel HD 620 with latest update (24.20.100.6229)
