I have Windows 7 install ISO. I use it to install test environment.

The problem is that I need to reinstall the environment often. And each time I have to install all the updates via WindowsUpdate.

I can see that each time the updates are downloaded to %WINDIR%\SoftwareDistribution\Download\

How can I merge these updates to the ISO file so they are installed all together?

You can't use the files from %WINDIR%\SoftwareDistribution\Download.

Use WSUSOffline to get all required updates. Install the Deployment Tools from the Windows ADK. Now mount the Install.wim from your DVD to a drive like C:\7work\Mount. Copy all updates to a folder like C:\7work\updates.

Now run DISM /Image:C:\7work\Mount /Add-Package /PackagePath:C:\7work\updates. This adds all updates into the image. Use DISM /Unmount-Wim /MountDir:C:\7work\Mount /commit to save the changes and unmount the WIM.
