Any body know the registry keys to change both Intel Graphics Power Plans (Plugged In & On Battery) to maximum performance through registry ?

I recently upgraded an old Windows 7 GMA laptop to Windows 10 to benefit from free upgrade before it terminates in December , problem is GMA driver of both Microsoft and Mods (Since Intel didn't bother making one) have GfxUI.exe either stripped off or blocked from running by windows so I have been googling how to apply optimized settings through registry directly , succeeded with 3D settings but not Power (Which actually make all the difference) .
