Add Microsoft Updates to an Image Using Windows Update Standalone Installer (Standard 7 SP1)

7/8/2014

It is important to keep your software up-to-date with the latest updates from Microsoft. Often, these updates are installed automatically using the Windows Embedded Standard 7 automatic updates feature, but occasionally you must install updates manually, for example if your image is offline or if it is not connected to a network.

This guide will step you through the process of installing a Standalone Microsoft Update Package to an image using the Windows Update Standalone Installer (Wusa.exe). You can use Wusa.exe if you want to install a Windows Update at a command prompt or a script. If you wish to install an update to an offline image or if you are installing a number of updates at once with an answer file, you may need to use Deployment Image Servicing and Management (DISM).

This guide assumes that you will install your updates using the answer file enclosed in the Microsoft Standalone Update Package (a .msu file). If instead you are planning on installing a number of updates or are including the updates as part of a configuration set, you may wish to create a custom answer file using Image Configuration Editor.

The Standard 7 setup process performs several verifications, which rely on the target device's date and time settings. For optimal performance, confirm that the target device is set to the correct date and time.
  • You have installed Windows Embedded Standard 7 Toolkit on your development computer. See Install Standard 7 Toolkit on a Development Computer.
  • You have downloaded one or more Standalone Update Packages (.msu files) for Standard 7 from Microsoft.
  • To use the Windows Update Standalone Installer on a Standard 7 image, you must install the WinEmb-Servicing-WUSA package on the image.

This guide assumes that you are familiar with Microsoft Standalone Update Packages (the .msu extension). These files are associated with the Windows Update Standalone Installer (Wusa.exe) and contains Windows Update metadata, one or more .cab files, a .xml file for unattended installations, and a properties file.

This guide also assumes that you have a basic familiarity with technologies such as Image Configuration Editor. For more information about these technologies see Standard 7 Basics.

  1. These steps assume that your image has the WinEmb-Servicing-WUSA package installed and that you have downloaded a Microsoft Standalone Update Package for Standard 7 from Microsoft.

  2. When you update an image at a command prompt or using a script, you should use the Windows Update Standalone Installer (Wusa.exe) to install an update. Type the following to install an update without user interaction, replacing <msu_file> with the full path of the update msu file you wish to install:

    wusa.exe <msu_file> /quiet

    The Wusa.exe file is a tool used to install Microsoft stand-alone update files. It is contained in the %WINDIR%\System32 folder. The Windows Update Stand-alone Installer uses the Windows Update Agent API to install update packages.
