Graphics Driver update for Bootcamp 6.0 Issues

After making a fresh install of Windows 10 1607, I proceeded with installing Bootcamp drivers AppleBcUpdate.exe on my MacbookPro 11,5 i7 Dual Graphics.

Everything worked fine after restarting once the installation was done. Now, I checked Apple Software Update and it gave me a few updates. Specifically the bottom three in the picture below.

It restarted after that and then "Apple Software Update" updated itself twice before offering a new update to the Graphics Driver.

This update screwed up the system. Auto brightness doesn't work anymore. Brightness keys don't do anything at all. I reinstalled bootcamp on a fresh drive just to isolated this issue.

Does anyone have a solution to this? Any suggestions? If anyone from Apple ever bothers to read this, then please test your drivers before sending them out.

MacBook Pro (Retina, 15-inch, Mid 2015), Windows 10

I had the same problem after the update in Windows 10 but these steps worked.

After updating the drivers go to Device Manager. Check Monitors > Generic PnP Monitor was disabled. Open the property and click Enable Device. F1 and F2 brightness control became functional again. For an unknown reason when you press F2 to 100% bars, there seems to be more increments of brightness beyond the Macbook maximum.

I had the same issue Clean Install windows 10 again before you install the bootcamp software delete the AMDgraphics folder inside the amd folder in drivers AMD on the installer drive replace the 13 version driver with the version 15.302 driver unzip the driver zip file create a new AMDGraphics folder inside the AMD Folder place the large list of files like setup.exe inside that new folder just like the old folder before you delete the old one look at the layout copy it the same install the bootcamp software then you will be offered version 17 in 6.3 bootcamp driver update if you install version 15.302 you will have a working brightness controls after 17 update 13 is junk it doesn't update correctly so just install 15 as a clean install no issues after I did this it works here the apple 15 driver page only download version 15 do 17 via apple software update http://support.amd.com/en-us/download/desktop/bootcamp

Remove Windows, re-install it, and create a Windows System Restore point, disable all Intel GPU updates, and then apply remaining updates and test.

The issue is not with the Intel GPU update. My system has Radeon M370X alongside.

The Graphics update that you see in the screenshot is an AMD driver.

The same rules apply for AMD. Create a restore point before you apply updates.

As suggested, I reinstalled Windows 10 and used the restore point feature to test which update affects the display brightness.

I can confirm that the Graphics Driver Update for Boot Camp disables auto brightness along with brightness up-down keys. Restoring to a Restore Point before installation of this driver restores display brightness functionality.

@Apple, don't update drivers when they break other system features.

Got the same issue - so annoying.

The Function + F2 / F3 keys don't work even though I have the function keys enabled in bootcamp settings.

Can't change brightness at all - no option in Windows 10 display settings and the only way I have found to adjust brightness is to go through the AMD Raedon settings control panel.

Terrible... Might go back to Parallels

Don't want to pave it yet. Will try a few more things.

If you were luck enough to have a system restore point to before the Graphic driver update, try restoring. I haven't had any issues with the old driver so far.

If you have time, you could try a fresh(painful) install of Windows 10, and this time ignore the Graphics Update.

No point in going back to parallels, you'll be taking a huge performance hit.

Hello i have the solution to his issue, you dont need to re-install windows, or downgrade any driver.

The solution is very sample:
1. Open windows menu and search for "Power Options", and launch it.
2. At the bottom you should see a screen brightness slider, slide it to any other value.
3. Press the key FN+F1 and then FN+F2 until the screen brightness is affected and the brightness level indicator appears in top left corner.

VOILA !

As a note: Even before updating you sometimes have to do this because the slider seems to be stuck arround 90%.
