Cannot Change brightness after upgrading to 1803 RTM, previously it was fine .

Anonymous

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.
