Are you having a growing number of virtual machines that may not be patched on a regular basis because they are offline? Wouldn't it be nice to have a way to maintain them with the most up-to-date security patches? Now, you have a free solution! Yes - FREE!
Introducing Offline Virtual Machine Servicing Tool (Beta)
The Offline Virtual Machine Servicing Tool manages the workflow of updating large numbers of offline virtual machines according to their individual needs. To do this, the tool works with Microsoft® System Center Virtual Machine Manager 2007 (VMM) and with software update management systems (at present, either Microsoft Windows Server® Update Services 3.0 (WSUS) or Microsoft System Center Configuration Manager 2007).
The tool uses "servicing jobs" to manage the update operations based on lists of existing virtual machines stored in VMM. Using Windows Workflow Foundation technology, a servicing job runs snippets of PowerShell scripts to work with virtual machines.
