I had to reset windows because on installing build 17127 , it botched. Even in the botched state it had no brightness control.

Now , I don't have it even after upgrading to 17133 or 1803 rtm . 

I have tried  , installing / uninstalling Intel HD graphics driver ( very old , core i3 first gen PC) 

I have installed/uninstalled Monitors >generic PnP monitor drivers .

(monitor.sys ) is the said driver that allows / disallows F2/F3 brightness hotkey , while brightness never changes. Can you give Monitor.sys from an earlier build such that it can be tested , how do I replace the driver.

    I upgraded to 1803 and my Laptop can't change the brightness either. So I'm not the only one with this issue. I had to roll back to a previous version in order to get that function back.

    My Laptop is from 2011 and it's the HP Pavilion G7-1070US. And uses the Intel HD Graphics.

    I created a backup of my windows 10 1803 using macrium. And reverted to the previous version. I will restore my backup until they fix this.

    There are many of us who have laptops from 2011. And they are out of warranty and the manufacturer no longer supports them. So I hope they can fix this.

    There are some compatibility issues with Windows 10 version 1803 and certain hardware or software. There is no explanation why a lot of these problems are happening in Windows 10 1803, but the release is significantly flawed. Software and Hardware that once worked in previous versions, just suddenly stops working in Windows 10 1709 after an upgrade and sometimes loses functionality or stability.

    Have same problem following upgrade to 1803:

    DellVostro 1540.

    Windows 10 Pro – Win 10.0.17134

    Intel Celeron P4600

    Intel HD Graphics Driver 8.15.10.2900

    Reinstalled graphics driver but does not resolve problem.

    Andre, can you advise whether compatibility issues are going to be addressed by a fix any time soon? From what you say, it sounds like this might be a fairly common problem with legacy hardware running 1803.
