The download mentioned in post #1 seems to be an iso. This is a DVD image file and must be burned to a DVD-R using Imgburn or similar. I think that method is aimed at IT professionals who need to update many systems. Most pc users get SP1 via Windows updates, although I guess the DVD method should also work for you. This is for info only, and I suggest you don't use the DVD method just yet, but follow NoelDP's instructions.
