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.

    Thank You, it will not be the first time I had to go to third party software.  Still want to fix the issue rather than work around it with my $.  Even though it's cheap money.  I don't understand why Microsoft can't fix their issue.  Maybe they will....ya right.

    Laptop display not dimming after Feature update to Windows 10, version 1803

    TOSHIBA Model: Satellite A665-S6050

    I went to Toshiba support and downloaded the last supported display driver (windows 7 64bit).

    Full function of Display control is back along with the Night Light. 

    I will follow up if the fix doesn't stay.  Note it may also have rolled back the sound driver, and power boost.  My sound is working, I don't use power boost.

    Did not restore the function key control.  Using display in settings, or notification quick actions are working.

    Thanks for the reply.  I will give it a try.  We also have a Levono Idea Pad P500 in the house, it also has no working brightness control.  Prior to the upgrade I think it was stuck on 50%, and looks like its now at 100%.  I gave feed back to Microsoft, but would be very surprised if our issues get fixed by an upgrade/patch.
