Boot Camp drivers don't always load (for Windows 7)?
Whatever you do in OSX is completely unrelated in how W7/8 behaves. Unless one of the apps you are using is VMware Fusion (dont know if Parallels can do this too) to access the bootcamp partition as a VM. 

I would highly reccommend reinstalling the WindowsSupport files created from the Bootcamp Assistant to see if that fixes the problem.
