This topic demonstrates how to use the Deployment Image Servicing and Management (DISM) tool to add a Windows® Preinstallation Environment (Windows PE) update to an offline Windows PE image. Most hotfixes from Windows Update do not apply to Windows PE for the following reasons:
Windows PE is a small subset of the Windows operating system.
Windows PE runs very few services.
To add a Windows PE update to a Windows PE image offline
Use the DISM tool to mount the base image to a local Windows PE directory. For example,
Dism /Mount-Wim /WimFile:C:\winpe_x86\winpe.wim /index:1 /MountDir:C:\winpe_x86\mount
Add an update to the base image by using the DISM command with the /Add-Package option. For example,
dism /image:C:\winpe_x86\mount /Add-Package /PackagePath:<full Path to a package>
Determine the name of the update by using the DISM command with the /Get-Features option. For example,
dism /image:<path to image> /Get-Features
Note By default, the state of each package is set to "Enable Pending", which indicates the Optional Component is installed and enabled. For more information on the /Get-Feature option, see Enable or Disable Windows Features Online.
Repeat for each additional update.
Commit changes to the image. In this step, you commit the changes to the original image file by using the DISM /unmount option with the /commit option. For example:
Dism /unmount-Wim /MountDir:C:\winpe_x86\mount /Commit
