hello , Yesterday I installed the 1809 update , and today i noticed that each time i restart my laptop the brightness level is being reset automatically to 0% or 25-50 i'm not really sure , and after windows will boot up , i will need to manually adjust the screen brightness again to 100% . I searched the web and i found this https://www.windowscentral.com/windows-10-october-2018-update-common-problems-and-fixes#fix\_brightness\_windows10\_1809 , and it might be an update issue i think  , by the way , my power plan is set to maximum performance and my laptop is always plugged in , and solutions or ?

    This might work but there are also other registry keys that probably can be used in this case. However I assume this has nothing to do with actual discussed problem in this thread. Because "FeatureTestControl" modifications are typical used for Intel Graphics when the brightness control is permanently and completely stuck. At least in my case this way the case.

    I leave also some reference on this problem. I have/had this will with my XPS 14 when I update Intel drivers to generic ones.

    reference 1

    reference 2
