No, Windows Update's Nvidia driver set is usually years out of date and rarely gets updated. It exists as an emergency fallback and doesn't push out regular updates.
Perhaps nVideo should request access to a dpecial 'this is less crap' process and help MS understand how dangerous is the previous crap it approved.
Because I don't use my PC to play games and thus don't need anything more than run-of-the-mill graphics acceleration, I'm loathe to download NVIDIA's enormous drivers, which I assume contain extraneous features and utilities that are useless to me.
