I am not an employee of Intel and so are not in a position to affect their drivers. I did though find a guide that suggested the following process for fixing the brightness function key:
1. Go to Device Manager > Monitors > Generic PnP Monitor
2. Right-click on.'Generic Pnp Monitor. If the menu says 'Enable' - meaning that this monitor setting, and thus the brightness function key, is disabled - then click on Enable.
I have exactly same issue with Asus UX501VW, with Intel HD Graphics 530.
The issue still exist in latest 126.96.36.19982 driver.
Brightness can be changed in Mobility Center, or in display settings, so it's not about inability to change brightness at all.
It's just Fn+F5/F6 doesn't work, like reassigned to something else, or completely ignored.
"Solutions" like 'reinstall ATK' or 'Enable Generic PnP Monitor' won't help.
There is a newer version of ATK you can try: http://dlcdnet.asus.com/pub/ASUS/nb/Apps_for_Win10/ATKPackage/ATKPackage_Win10_64_VER100057.rar
uninstall old version
ignore error message from USB charger
install new version

How to reproduce
Please provide steps to replicate the issue. These steps are very crucial to finding the root cause and fix.
A screenshot to illustrate the issue is a huge plus. A video of the failure is even better! Attach to the post or provide the YouTube link.
- Rebooted into safe mode and used DDU to uninstall the Intel HD graphics driver 184.108.40.20673 and rebooted
- I then installed Intel HD driver 220.127.116.1149 and rebooted
- The Fn + Brightness keys now work
- Windows Update installs the new Intel Graphics driver 18.104.22.16873 and, upon reboot, the Brightness keys stop working
The system BIOS on my laptop is 1.05.08. Please fix this issue as quickly as possible.

Thank you for your response and I understand that you are currently experiencing issues with the "FN" brightness of your system.
First, I would like to start by letting you know that the FN or function key is added by the different system manufacturers and not by Intel ®. If this was a graphics problem then the solution would be to use the latest graphics driver from the system manufacturer.
Now, I say to use their driver because we supply generic versions of graphics drivers for general purposes. Computer manufacturers can change the features, incorporate customization, or make other changes to the graphics driver software or software packaging. To avoid potential installation incompatibilities, we recommend that you first check with your computer manufacturer and use the driver software provided.
I found the following support site with drivers:
* Please be aware that the content on that site is not controlled by Intel*. This information is offered for your convenience and should not be viewed as an endorsement by Intel* for the merchants or services offered there. *
Please try that driver and then let us know if the problem persists, however, as mentioned, the FN key is added by the OEM so in this case I would also recommend to get in contact with Asus*.
