When you are servicing an offline image that has pended content and then try to add a package by using the Deployment Image Servicing and Management (DISM) command-line option /Add-Package /PreventPending, the package is not installed. The /PreventPending argument can be used successfully only when you are servicing an image that has no pended content.
If you service the image by using the /PreventPending argument despite the presence of pended content, the package is falsely reported as "installed" even though no installation operation is complete. At this point, the only way to confirm which servicing operations were successfully completed is to boot into the image. This lets you verify what is installed.
