Next Tuesday, 1/22/08, we are adding a new product family to your WSUS server - Expression. The Expression product family will include updates for all Expression products, including service packs, optional updates, and critical or security updates. For additional information on Expression Studio Products see: http://www.microsoft.com/expression/. Tuesday, 1/22/08 we will be publishing the first Expression Media Service Pack (SP1) to the Microsoft Update Site, and making it available (depending your on settings ) via Automatic Update, and to Windows Server Update Services (WSUS).
We recommend WSUS admins having Expression deployments in their corporation; select this new product family to synchronize associated update classifications of your choice. Additionally, Expression updates will be available from the Microsoft Update Catalog http://catalog.update.microsoft.com.
