MacBook Air 11.6, Windows 7
After installing the windows 8 do not run boot camp from setup, but install the individual driver from the windows support folder. Do not install the programme, driver in NVIDIA folder instead delete this folder and download new one from NVIDIA Site some thing like 310 in its name and install. After restarting run windows support folder setup file but only after deleting the NVIDIA folder only. Every thing works. The culprit is the NVIDIA folder in the windows support folder.

Booting through default rEFIt breaks the brightness controls in Windows 7.
A similar problem exists with the updated rEFInd package.
A temporary fix for brightness controls after installing rEFInd is to boot your machine via the Option Key, then select the "EFI Boot" option (replacing the Macintosh HD option), which then loads rEFInd.
Yes I had such problems on my MBA with screen brightness (and then, screen flickers and vertical coloured lines as if the screen was broken, but it was just, i think, refit wrecking the efi or whatever), on my new MBP now, I have not touched rEFIt with a 60 foot pole, and instead, make the bother to press alt every time I start the macbook, and have that as an effective anti-theft measure anyway - harder to detect my windows os, and i have no password on my never-really-used mac os x partiion, so when they turn it on after stealing it from me they're lured into a beautiful-looking honey trap, filled with screenshot-and-keystrokes-and-webcam-images-dropbox-saving spy tools, things like Prey service for remotely sending you IP addresses/Google Wi-FI GPS-like geo-location info, and functions to wipe your windows OS silently from within the mac partition :P. So I think that's a smart way to do things anyway. JUST USE ALT :).
BTW Vlad I've been watching this thread and want to just say, you are awesome and keep working on those issues and show apple you can do better than them! I hope you can work out that issue that you said Apple wouldn't share their solution to - keep searching <3.....
I HAVE FOUND A SOLUTION!!!!!!
The problem is due to Adaptive Brightness.
This is what you need to do if the screen does not go past a certain brightness level on Windows 7 or Windows 8.
Everything should be working now! Yay me! 🙂
6 month ago "tassoart" posted the same solution in this very thread.
Yay both of you!
Also if you have a light sensor on your device (iMac or Macbook), enable the sensor from ControlPanel-->Location and Other Sensors. once you have enabled it; your screen will adjust its brightness according to the light conditions of the environment.
Cheers
^This. When my backlight flipped to totally on, it was like a breath of fresh air - I literally "ahhhh'ed" out loud. Thanks dude.

1. Open Device Manager (Right click in the bottom right corner of the screen, click Device Manager)
2. Expand the Monitors
3. Right click on "Generic PnP Monitor" and choose Disable
4. Reboot
I have been having the issue of no brighness control when running windows through bootcamp for about 6 months now and have not found any applicable solution online.
While messing around trying to figure it out yet again I noticed that my monitor driver was signed by team viewer...
Sure enough clicking the roll driver back button resolved the issue by rolling the driver back to the Microsoft driver...
So long story short:
Right click "My Computer" click properties
Click device manager (lop left of window)
Expand Monitors section
Double Click monitor
Click driver tab
If the driver here is not signed by Microsot or Apple click the roll back button. My driver version is 6.1.7600.16385 (Driver date 6/21/2006)
Rolling this back instantly resolved my issue. I will now propagate this post to all the threads I saw regarding this issue.
I am running windows 7 x64 Ulti on a 15" rMBP.
Best of luck
Excellent , thanks for this just reinstalled with Windows 8.1 and this fixed me up no probs
Kevin, you re-installed Win 8.1 from scratch to fix this? Formatted the whole drive?
My brightness control stopped working after 2 days. There's no guarantee that it won't do the same thing again even if I reinstall Windows.
How's it going so far?
You can go to Control Panel -> Power Options, there is a screen brightness slider in the bottom of the window
I went up to step 5, but after that I don't see the word "Enable Adaptive Brightness" at all. I'm using window 7 on a macbook air. I've been trying to figure this out for awhile now and the screen light is killing my eyes. Especially during the night.
Went to Control Panel, but I don't see "Location and Other Sensors" on it. Using Window 7 on Macbook Air.
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.
