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 ?

    Hi everybody...my Dell XPS 13 9360 brightness adjust not working after leaving from Suspend mode, since version 1809 update ....last KB4469342 did not solve the issue.

    Did you reboot? You have to restart before the fix will take hold.

    It does work here....

    So how long until this fix reaches everyone? Currently in Spain, no update yet.

    Restarting restores the brightness adjust, but following any Suspend it freezes again. Only restarts work temporarily, turning off and on again has no effect.

    Yes, there's something completely klutzy about this 'fix'...

    I had it fall me when an MS installer called its own restart -- not bothering to try to figure out all ways this fails.

    My brightness control is a key, so just lean on it on startups when required, saves this waste of time.

    ...and... Yesterday the laptop let me know another update was being loaded -- with exactly the same KB number as the fix a day before.

    This time, restarts do continue with correct brightness, at least so far.

    Crossed fingers, but in any case, at least there's a finger workaround if the round-about turns out still not right...
