Along the same lines as our previous post on customizing offline servicing, this post details how to specify the drive where the Operating System task sequence media creation process stores its temporary files and mounts WIM images. This includes bootable media, standalone media, prestaged media, capture media as well as the new Virtual Hard Disk feature of System Center 2012 R2 Configuration Manager.
