Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support.
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 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.
Same with mine
Dell XPS L501X
Intel i5 CPU M 460
Win 10.0.17134
Intel HD Graphics 8.15.10.2900
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.
Same issue here with my acer notebook
