Compacting Virtual Hard Disks in Windows 8 / Windows Server 2012

Recently the “Ask the Core Team” blog did a great post about compacting a dynamically expanding virtual hard disk in Windows 8 / Windows Server 2012.  You should check out their full post for the details, but the summary is that you now need to manually mount the virtual hard disks in the management operating system prior to trying to compact it.

This is something that we used to do automatically for you – but we had reports of problems when we were attaching and removing virtual hard disks when the system administrator was not expecting it – so we have changed this to a more manual process.
