Update Windows/Bootcamp from new drivers installed on OS X?

Alright, I just installed new drivers for a Quadro 4000 Graphic Card on the Mac side OS X 10.6.8. The thing is that when I booted on the Windows side it freezed, probably because it didn't recognised the new drivers installed on the Mac side.

I'd like to know, does it's have a way to update Windows so he update the new drivers added on the Mac side?

Not sure if I'm clear here, let me know if you don,t understand something.
Thanks!

Alright thanks for telling. The issue though is that I can't download drivers on the Windows side. I can't get them on NVidia web site.
