I have a Retina Display MacBook Pro with the latest OSX and also installed Windows 8 RTM on BootCamp.
I hadn't logged into BootCamp in a few weeks, so I dont recall if the backlit keyboard ever worked on bootcamp or not. The thing is, I haven't been able to make it backlit.
I installed Power Plan Assistant (and Trackpad++), and the "Turn Off backlit keyboard" option doesnt do anything. I thought if I clicked on it, it'd toggle whatever setting it is it uses to actually turn it off, and I could use that to turn it on.
As far as I know, I have the latest bootcamp drivers (i update anytime I get an alert about that), and the latest windows drivers on the bootcamp install.
I've googled extensively about how to manually turn the backlit keyboard on on a bootcamp partition, but haven't find anything. I tried dimming the display to 0, then to the max, and that doesnt work.
If it helps at all, my function keys don't work either on bootcamp.
Any ideas?

Keyboard lights work perfectly in both W7 and W8. (and Fn F5 and Fn F6 control the intensity)
Try reinstalling the WindowsSupport files (which reinstalls the keyboard driver), you should not lose T++ functionality, but if you do just reinstall it (Power Plan Assist reinstallation is not needed)
Sometimes after some sleep-wake cycles the dimmer function stops working (Pressing Fn F5-F6 brings up a gray panel with a disabled sign), rebooting fixes the problem.
