Not a whole lot to say here, but if you're running Vista on an x64-based system, you've probably already noticed a little surprise courtesy of Windows Update, which today started pushing out the x64 edition of Vista Service Pack 1. If you've been following things in SP1 land, you'll notice that's actually ahead of the neat and tidy Windows Update launch for non-x64 systems, but behind the unofficial options already available. On the upside, that should mean that all the bugs have been ironed out, but you can never be too careful, so take all your usual pre-update precautions and let us know how it all works out in the comments below.
