The first service pack for Windows Vista has just been released. It doesn't look like there are any huge changes to the real meat of the operating system. The update seems to mainly address some stability issues and a few small performance issues. To read a full review of the upgrade check out the great write up at PCPRO. If you are interested in all the little details here a link to Microsoft's list of notable changes.
Vista users that can't wait to upgrade should open their start menu, click the all programs button then click on windows updates to get to the windows update center. If you don't see the service pack 1 update do all other available updates and try again. If you still don't see it you may have to wait just a little longer. Apparently there are some drivers that are having issues with service pack 1 and Microsoft is holding out on providing the update to computers with those drivers until the problems have been fixed with driver updates. The good news is that Microsoft says they will send the driver updates out through windows updates over the next couple months which will unlock the update for many users. Users desperate to upgrade can find a manual installation on Microsoft's website but i wouldn't recommend it.
