We're just switching our images over from good old ghost .GHO's to .WIM format. One of the reasons is that we have heard that software updates could be modified/installed in .WIM's offline.
For example, right now if we wanted to move from Adobe Reader X to Adobe Reader XI, we would need to drop our base, uninstall Reader X, install Reader XI, reseal our sysprep'd image, then recapture in Ghost.
Unfortunately the only process I can find looks like it only applies to Windows Updates. Other walkthroughs I've found show how to deploy the software as part of a task sequence in SCCM which I don't have access to and our customer does not actually have the network infrastructure to support.
Is this possible or did we misunderstand the scope of the offline updating feature?
