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.
