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 ?

    I went into services.msc but I couldn't find the displayenhancementservice. I looked in two laptops and it wasn't there. Am I looking in the wrong place?

    I have the latest (non beta testing) updates,  surface go, and I have the issue. The only "solution" is to restart or uninstall/reinstall the drivers. But by next reboot/ shut down and start it will habe again the issue. In my other Asus PC I have wifi issue after sleep (I have to turn off and on)...

    While most posters have third party hardware, I'm actually on a Surface Pro (2017) and the brightness level was fine up until the OS did a small "feature" update the other day. Now 100% looks more like what 50% looked like before. 

    This unit runs Intel HD Graphics 615. I tried doing a driver update but it says I have the best driver loaded. I greatly disagree with that statement.

    Hopefully MS or someone with additional knowledge can post a solution to this.

    Thanks

    This is really crazy. I have ASUS UX ultabook and since 1809 I have 2 problems. One is SIMILAR to this. The difference is that the slider is NOT at 50%, the slider is at 100% but the brightness is at approx 50% !!!

    I tried updating the driver for Intel, NVidia, I even installed insider's preview of Windows but the issue remains!

    The thing is that when I turn the notebook on, the display is at 100% on lock screen. As soon as I logon, it is reduced to like 50% and it can be adjusted, but the maximum brightness is not 100%!

    The other problem is that sleep mode doesn't work, but that is for another topic...

    I'm experiencing this exact issue (Windows says 100% brightness, brightness is actually 50% when on battery) with my HP ZBook 14 (Gen 1). A reboot sometimes fixes the issue, but that's barely an acceptable workaround. I have installed the latest BIOS and display drivers from HP.
