Screen Brightness in Bootcamp Windows 10 Preview

I was running into the same problem when I upgraded from Windows 7 to Windows 10. After searching through the settings, I found a solution that appears to resolve this issue.

To fix this problem:

1. Go To - Settings>System>Display
2. Turn Off "Adjust My Screen Brightness Automatically" Setting

I hope this helps. If anyone is having problems with Windows 10 bootcamp, I would strongly recommend installing the most up-to-date bootcamp drivers. I lost my F-key functionality after the upgrade, and reinstalling the updated drivers resolved that issue.

The following link explains the process to reinstall updated bootcamp drivers:

I am facing same issue the brightness bar goes up and down but there is no visible change in the brightness. I have tried disbling the adaptive brightness and automatic brightness settings but still it doesn't seem to work.

Please can someone help.

I did a fresh install on my macbook pro retina 13 inch using the latest bootcamp drivers. THanks

This help me. Thanks.

This solved my problem as well. Thank you for posting the answer 🙂

Disabling Adaptive Brightness in Windows 8 or 10

Hit the Windows key, and then type in “Power Options” into the search, which will pull up the Power Options panel.

Once here, click the “Change plan settings” link on the selected plan.

Then click the “Change advanced power settings” link.

And now, browse down to Display –> Enable adaptive brightness, and change the settings there to Off.

Changing this setting fixed my brightness problems on my MacBook Air running Windows through Boot Camp.
