Modifying CM 2007 service window cause unexpected delay in Updates deployment

A new Knowledge Base article (KB2850370) recently published for ConfigMgr 2007 talks about a rare issue that we may run into if we modify the properties of a maintenance window right after creating a new software update deployment.

Article Title: Modifying a Configuration Manager 2007 service window may cause an unexpected delay in a software update deployment

The article says that the software update will still get deployed on the clients but may happen a little later than we might expect. This is by design in System Center Configuration Manager 2007.

ConfigMgr Patch Installer Tool/Script

   The ConfigMgr Patch Installer is a tool (vbscript) which can be used for installing updates which are advertised from SCCM. If the updates are advertised without a deadline. Especially it is useful for Windows Server 2008 Core edition as they do not have a GUI and so the updates can't be installed. This tool will query SCCM for each Update which is advertised to the System and will install it. The result can be displayed in a output logfile.

The Tool can be downloaded at:
