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 also have the same problem with an Acer Notebook. The brightness is set to maximum and I cannot change it. When I deinstall the Intel HD Graphics display driver I can set the brightness. The same driver worked for years under Win 10.

    Had the same issue with a Dell Inspiron 15 N5040 with an Intel i3 380M. I will downgrade as it worked on all previous versions of Windows.

    Quick Update - It appears the actual graphics driver component is completely fine, as when I reinstalled it, it became stuck at full brightness.
