Q: Screen Brightness in Bootcamp Windows 10 Preview

I recently installed the Windows 10 Preview via Bootcamp on both my 2012 iMac and 2012 MBP both with Yosemite. Both installations went fine except for the MBP's screen brightness. It will only go to about 75% brightness even though it says 100% leaving me with a pretty dim screen. The bootcamp drivers seem to be working fine because I can adjust it both up and down, it just won't get as bright as it should. If any more information is needed please let me know and I will post that info. I really need this problem fixed.

MacBook Pro, OS X Yosemite (10.10.3)

    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
