    I fixed it.


    Hello my friend, I had same issue about brightness of my Macbook Air (late 2010). I installed windows 7 home premium and after having my updates i noticed that brightness was not working. i tried to find some answers from here and found this discussion. However as I can see, no one have answer for this.


    Today I just uninstalled Nvidia Gforce update. than i Uninstaled Nvidia control panel. it asked me to restart my mac, and also when it asked restart, the resolution was 800X600 or something like that. It was very big icons. however, after restarting my mac, it gaved me notification that it found video card in this Mac and asked to restart again. i restarted and its gone. now resolution is fine, and F1, F2 brightness buttons work well.. i hope you will fix it.
    By the wey, now i entered to control panel>>Programs and features, and there still exist this ones: NVIDIA display control panel / NVIDIA Drivers / NVIDIA Graphics driver 327.02


    Tell me if you can fix it like this.

    I have a MacBook unibody, late 2010, running Windows 7 Home Premium x64, and also ran into this same problem (no dimming controls) after installing the latest video drivers for the GeForce 9400M. I fixed it by rolling back to the previous driver, as follows:


    1. Control Panel -> Device Manager

    2. Expand "Display Adapters", right-click on "NVIDIA GeForce 9400M", then select "Properties"

    3. Switch to the "Drivers" tab, then left-click "Roll Back Driver"

    I have a MacBook Air running Windows 7 with bootcamp. The brightness control buttons no longer work after the 310.xx driver. Issue has been fixed after alittle bit of research. Thanks all who participated the bits and piece of this resolution. Start off by installing the latest NVIDIA drivers and latest Bootcamp. Yes you heard me correctly. No need to roll back, the latest and greatest worked for me. version 337.88
    1) Go to control Panel, then device manager, then under "Monitors" I've Disabled the "Generic PNP monitor"
    2) Open regedit and go to the HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/Control/Class/{4D36E968-E325-11CE-B FC1-08002BE10318}/0000
    3) Add a new DWORD called "EnableBrightnessControl" and set the value to 1.
    4) Reboot and the brightness keys should work again.


    Have fun!!!

    You can fix it installing the last bootcamp version and drivers and by adding the regist automatically entry by using the following file from my creation:



    If you find compatibility problems installing the last bootcamp version:

    1st go command prompt (start-->type "cmd"-->execute it as admin)

    2nd type cd in the command prompt and go to the apple folder of bootcamp directory

    3rd type msiexec /i BootCamp.msi (or BootCamp64.msi or BootCamp32.msi) and finish installation.


    Thanks to Foffa101. Regards.
