Use the offlineServicing configuration pass to apply unattended Setup settings to an offline Microsoft® Windows® image. During this configuration pass, you can add language packs, updates, device drivers, or other packages to the offline image.
The offlineServicing configuration pass runs during
Windows Setup. Setup extracts and installs the Windows image,
and then executes the Deployment Image Servicing and Management
(Dism.exe) tool. Packages listed in the
<servicing> section and settings in the
<offlineServicing> section of the answer file
are applied to the offline Windows image.
Additionally, you can use the Dism.exe tool with an answer file to apply settings in the offlineServicing pass.
