Microsoft updated this tool to include support for Windows Server 2008 R2 and VMM 2008 R2. What does it do?
What it does is allow you to update VM’s that are offline and stored in your VM library. A scheduled job runs, deploys the VM, updates it and stores it back in the library.
It does not work with templates unfortunately. I have no need to store VM’s in the library but I do have a tidy little collection of templates stored away (MS just refers to them as VHD’s, templates are a different thing altogether in VMM-speak) and I have no choice but to update them by hand.
Version 2.1 of the tool now works with System Center Virtual Machine Manager 2008 R2, System Center Configuration Manager 2007 SP2, and Windows Server Update Services 3.0 SP2. The tool also supports updating the Windows® 7 and Windows Server® 2008 R2 operating systems.
