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 ?

    What a shame, this is going to create a lot of returned laptops this holiday season!  Now I have to decide if i'm going to keep the freshly installed 1809 on my brand new Evo 970 or put more wear and tear on this brand new drive.  Sadly, 1809 is considered stable by Microsoft and is the only version available to download when using the Media Creation Tool.

    I have the Intel UHD 620 Graphics (4K display) in an HP Spectre x360 13t and the upgraded graphics driver did not fix the issue for me. I've seen different results with different versions of Windows 10. I'm running the Enterprise version.

    Hi,

    The answer is updating your graphics driver. I have updated my Intel Graphics Driver here

    https://downloadcenter.intel.com/download/28180/Intel-Graphics-Driver-for-Windows-10?product=80939

    I've tried to update my driver and now it is fixed.

    Hope it helps guys.

    Same for me, it worked.

    Intel HD Graphics 620

    This new DisplayEnhancmentService is applying a hardcoded brighness on every boot

    located at

    [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\DisplayEnhancementService\State\LGD03030_00_07DA_C4]

    LGD03030_00_07DA_C4 (is my monitor yours will be different)

    "SliderBrightnessPercent"=dword:00000032

    "ScreenBrightnessPercent"=dword:00000032

    you will have to take ownership of State then give your self write permissions

    and set

    "SliderBrightnessPercent"=dword:00000064

    "ScreenBrightnessPercent"=dword:00000064

    this then forces 100% on every boot

    or better still disable DisplayEnhancementService and the value set by your self will be respected on every boot

    atleast in the case of my Vostro 3750 (4 hours old install of the latest October 2018 Update on a secure erased ssd)
