    Hi to all,

    I don't know if someone already posted this but I found in another forum the following method to restore the max brightness level:

    Go to Device Manager ==> Display Adapter ==> Right Click on Intel UHD(or your main graphics adapter) ==> Disable Device ==> Then ENABLE Device

    Instant fix :)

    I have a Lenovo y520 and it's a workaround at least. Hope windows will fix this issue soon.

    I'm having the same issue, where the screen occasionally resets brightness to 50% or so. It started immediately after installing the October update. It seems like Microsoft tried to migrate the adaptive brightness away from the classic Power Options and into the new Display Settings, but left out the small detail of actually adding the setting. It's referenced in Ease of Access that you should be able to change adaptive brightness in Display Settings and it even links you there, but the option doesn't exist.

    I've dug around in the registry a bit, and I managed to find this directory: HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\DisplayEnhancementService\State\SDC434B0_00_07DE_2B

    which includes options like, "isAutobrightnesson." I haven't had a chance to try editing these keys, but it looks very promising. A word of warning, editing the registry can cause serious issues if you don't know what you're doing. Do so at your own risk.

    5. Expand **Enable adaptive brightness,**then **** turn OFF the settings.
    6. Restart the PC.

    Hope it helps.
