How to create a Windows 7 SP refresh media

win7Sometimes it's mandatory to re-install Windows 7 SP1 on a machine. The question is, who to proceed to setup an up to date system with minimum efforts. Microsoft has published an answer to that question.


My MVP colleague Mike Halsey recently mentioned within a tweet this related Microsoft Technet article. All you need is a Windows 7 SP1-ISO install media. Then the following updates are required additionally.

  • KB3020369 (April 2015 Service Stack Update)
  • KB3125574 (April 2016 Convenience Update Rollup)
  • KB3177467 (September 2016 Servicing Stack Update)
  • KB3172605 (Juli 2016 Functional Rollup Update
  • KB3179573 (August 2016 Functional Rollup Update)
  • KB2841134 (Internet Explorer 11 – optional)
  • KB3185330 (October 2016 Monathly quality update)

All links are pointing to Microsoft Update Catalog, where you can download the update packages. The Internet Explorer 11 update is optional.

If you plan to integrate the updates mentioned above into an install.wim shipped with the ISO image file, you have to extract the .msu filtes. After extracting, the .cab files should be present within a local folder.


Delete all files, except the .cab files shown in the screenhot above. The mount the install.wim obtained from an ISO file using DISM.


Dism /Mount-Image /ImageFile:C:\test\images\install.wim /Name:"Windows 7 ENTERPRISE" /MountDir:C:\test\offline

Then you can add the above .cab files using DISM commands like this:

Dism /Image:C:\test\offline /Add-Package /PackagePath:C:\files\Window7MediaRefresh\CABs\

Unmount the image using the following command:

Dism /Unmount-Image /MountDir:C:\test\offline /Commit

All steps are discussed in details within Microsoft's Technet arcticle. Then you can insert the install.wim into the ISO install image using AnyBurn or similar tools.

      Imho not necessary. If you use Media Creation Tool, it will include some refreshed ISO images. And then the latest cumulative update should bring your system to the latest patch level – imho.
