    Brightness Control Bug


    I've been poking at this a month or more now and don't think I'm any closer to figuring out what's causing this very odd problem with windows 10


    Standard User profiles on my machine cannot use any brightness controls unless I switch to an admin account first to 'kick start' the machine recognizing its brightness settings. Then after switching back to a standard user profile I can use all brightness controls again as normal... but only until the machine goes to sleep. As soon as the screen goes dark for any reason when it goes right back to 100% brightness and standard users being locked out of these controls.


    I've tried;

    Updating all drivers, nothing

    Deleting and then reinstalling all display drivers, no help

    Admin level sfc /scannow, and found no issues,

    Deleting and completely recreating profiles many times. No change. Editing registry suffix on the effected profile, Still no change.

    (re)disabling adaptive brightness controls


    I've played with every display/power setting I can think of and rebooted in all manner of combinations...


    What is going on and how do I fix it?

    :)

    Brightness Control not working in Windows 10

    Hi Ella,

    To adjust the brightness, see the steps below:

    • Go back to Power Options, and tick on the High performance.
    • See if you can adjust the brightness.

    If this not work, we highly suggest that you create an Administrator account, and re-do the steps above.

    Let us know how it goes.
