Temporarily Disable the Windows XP SP2 Automatic Download

How do I temporarily disable the automatic download of Windows XP SP2?

Windows XP SP2 was released to the Windows Update – Auto Update tool in the middle of August 2004. While recognizing the security benefits of Windows XP SP2, some organizations have requested the ability to temporarily disable delivery of this update via Automatic Updates (AU) and Windows Update (WU). These organizations have populations of PCs, upon which they have enabled AU. This is done to ensure that these PCs receive all critical security updates. These customers would like to temporarily block the delivery of SP2 in order to provide additional time for validation and testing of the update.

At the end of this period, Windows XP SP2 will be delivered to all Windows XP and Windows XP Service Pack 1 systems, but still download other critical updates.
