Did you install the Windows support software? If not, start up in OS X by holding the Option (Alt) key while your Mac is starting and choosing your OS X partition. Then, open Boot Camp Assistant (in /Applications/Utilities), mark the box to download the Windows support software and follow the steps. Finally, start in Windows and install the Windows support software.
You can also select the MacBook Pro you have and the Windows version you have installed in this website to download the correct version > http://support.apple.com/kb/HT5634
