According to the Microsoft Windows Vista blog, today Microsoft released Windows Vista SP1 to manufacturing. Unfortunately it will not be until mid-March before it hits Windows Update and becomes available for download.
Today also Windows Server 2008 made it to manufacturing as well. As of a few hours ago Microsoft published the final versions for download in their MSDN Subscribers’ Download area.
Hopefully it wont be too long before Vista runs faster on my iMac thanks to the service pack.
