Don Smith shows how everyone should be using VPC Differencing Disks
post on how to leverage differencing disks in Virtual PC
is truly enlightening. I am the worst about creating ad hoc VPC images. I have one base image with WinXP SP2 and Office on it; anytime I need a new "machine" I copy that base image, run NewSid
, and start installing software. I know this is a waste of drive space (and effort), but I never really thought to much about it.
Well, I have now. Don does a great job of laying out how he uses his base images combined with differencing disks to support multiple envionments. This is kick ass stuff. I'm linking his VPC Model here, but go read the entire thing to get the details
