We need to deploy an update to Silverlight to allow one of our web based applications to run correctly. SCCM is currently configured to wait 3 months before expiring a superseded update. Microsoft released an update in Decembers patch release which expired the update that could of been deployed by SCCM. This latest update was subsequently expired by Microsoft meaning I have no updates available to deploy to the clients. My questions are:
1. If I increase the time period of 3 months to wait before expiring a superseded update, will SCCM rescan all updates and then make expired updates available if they fall within this newly configured time period?
2. If I then revert the setting after deploying the update will it then rescan again and make expire updates again that are older than 3 months?
