Support life cycle for Microsoft Software Update Services 1.0

In response to customer feedback, and in order to give customers more time to migrate off SUS 1.0, Microsoft has extended support to Tuesday, July 10, 2007. Microsoft will no longer support SUS 1.0 after this date.

SUS 1.0 will no longer synchronize new update content after July 10, 2007. Therefore, SUS will no longer help provide new updates after this date.

We recommend that you upgrade to Windows Server Update Services before July 10, 2007.
