Windows Vista SP1 is Now Available

Windows Vista SP1 is finally available for download from Windows Update.

If you have Windows Vista configured to download updates automatically then SP1 will start downloading to your computer automatically in mid-April. Just to make sure you know, Microsoft’s Windows Update will automatically download but will not install the service pack automatically.
If you don’t see SP1 as an option in Windows Update then you can manually download SP1 here. You might want to check this KB article before installing SP1..
