mbp 15" 2011, windows 7, help with minor issues

i have 2011 mbp 2 graphics cards. installed windows 7 via bootcamp. ran bootcamp software came in snow leopard recovery disk drivers , such.

when boot windows 7, keyboard backlight on full though turned off on last session on windows. screen brightness below halfway point though turned on last session on windows. why keep on happening , why "control panel" confusing. , finally, frustrating problem on "devices" or something, shows dedicated graphics card, , because of battery drains in 3 hours while working on ms office.

how can fix these problems?

 

the drivers came snow leopard disk pretty old nowadays, of them aren't compatible 64bit windows 7. best thing osx lion (if haven't) , let download bootcamp 4.0 drivers using bootcamp assistant. copy drivers usb stick or , quit bootcamp assistant. after can install drivers in windows side , issues fixed newer drivers.
