Temporarily Disabling WinXP SP2 Update

While recognizing the security benefits of Windows XP SP2, some organizations have requested the ability to temporarily disable delivery of this update via AU and 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.

Since SP2 will start to be delivered to PCs running Windows XP or Windows XP with SP1 via AU starting on August 16, these customers would like to temporarily block the delivery of SP2 in order to provide additional time for validation and testing of the update. In response to these requests, Microsoft is providing the following guidance, resources, and communication vehicles to meet the needs of these customers.

Please note that the mechanism to temporarily disable delivery of Windows XP SP2 will be available for a period of 240 days (8 months) from August 16. At the end of this period, Windows XP SP2 will be delivered to all Windows XP and Windows XP Service Pack 1 systems.
