My MacBook Unibody does not recognize my brightness control since I updated the NVIDIA driver in Windows 7 Bootcamp. Any solutions?

My MacBook with NVIDIA driver recently updated. This may or may not be related, but now my brightness control seems useless. Volume control, play buttons, keyboard brightness and escape key all work, but the brightness does not change.

The normal Display brightness bar goes up and down, and nothing happens.

I went into the Bootcamp Control Panel and changed the brightness, pressed "Apply" and nothing happens.

Has there been any update to fix this?

Driver Provider: NVIDIA

Driver Date: 5/15/2012

same problem here also....

i got one thing ....doing all time is annoying..

go to "device manager" and in that go to "display adapter" and disable "nvidia drivers" by clicking right click and selecting "disable" option ..... then system will run on windows graphics drivers...

then ur brigthness control buttons will work change ur brigthness to ur desire... and then go to same device manager and "enable" "nvidia drivers" ... brigthness will remain constant..

do this when ever u want to change brigthtness.... but every time u log into the system brigthness will at peak level..
