you can try... but windows will toss a hissy fit of large magnitude!
i tried when i replaced my motherboard, and i ended up having to reinstall ALL the drivers for the hardware, and it still didnt run properly. In the end it was easier to reinstall windows from scratch, allthough u could well do a reinstall over the top of the old one, and keep all your programs/link/setup etc.
