Windows Vista Service Pack 1 (SP1) Released
Microsoft released Windows Vista Service Pack 1 on March 18 in English, French, Spanish, German, and Japanese. You can get it from Windows Update or the Microsoft Download Center. In April, Windows Update will begin to download SP1 automatically but will only install it after explicit agreement of the user. In April, SP1 will also be available in the remaining 31 languages.
On some systems Windows Vista Service Pack 1 might not be available for installation from Windows Update and might not be offered by Automatic Updates. This can have several causes. If this is happening for you, check KB948343.
