Group: Awaiting Activation
After a little bit of thought, I think I might have come up with an answer.
The "Reference Image", in my case, is the OS I installed with all the customizations I made to it prior to sysprep-ing it and capturing the image.
The "Golden Image" is the imported copy of the above image that I saved into WDS, that will be used for future deployments.
So in my case, I never save the reference image after I am done importing it into WDS. Once I import it into WDS, where it becomes the golden image, I usually just wipe the drives of the reference computer and whack the image.
I then create a brand new reference image (on the same spare hardware) a few months later to update any software, drivers, or patches and then use that as the source of a new golden image. And the process repeats...
I am guessing there is probably a more efficient way to do this, that "keeps the reference image" so that I don't have to create a new one each time, and just update the existing one instead.
