The Service Pack Blocker Tool temporarily prevents the installation of a
service pack through Windows Update, typically for one year after general
availability of the service pack. We are announcing the upcoming expiration

SP3:
• Windows Vista SP1: April 28, 2009
• Windows XP SP3: May 19, 2009
After April 28th, Windows Vista SP1 will be delivered via Windows Update.
And after May 19th, Windows XP SP3 will also be delivered via Windows
Update.
