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:

To add a Windows PE update to a Windows PE image offline

  1. 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
  2. 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>
  3. 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 [auth_7_phases].
  4. Repeat for each additional update.

  5. 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
