Minimal Update Iso - Based on available updates only.

[traxtopel]

Is there an option to create an ISO based on available updates only?

Hello trexopel!

What do you exactly mean with "available" updates?

You can manually create ISO images via command line. The corresponding batch file is cmd\CreateISOImage.cmd. It lists the available parameters when started without any parameter.

i.e. to create a update iso with only updates still to be installed.
Exclude updates which are already installed.

This software is intended to update client/target computers regardless of their patch level.
How should the download part, which is executed on another computer, know about the target computer's installed or missing updates?

I fully understand that, my use case is virtual images which are at a known update level, the iso would be a safe way to inject updates.

The simple answer is: No, not possible. Missing updates are determined only at the target computer(s), not before.

Maybe blacklisting all slipstreamed / preinstalled updates?
Just for ISO: .\exclude\custom\ExcludeListISO-<OS>-<ARCH>.txt
For download and everything else: .\exclude\custom\ExcludeList-<OS>-<ARCH>.txt (I do not recomment this)
Syntax like the files in .\exclude;
for ISO:

Code: Select all

*<KB-number>*

for everything:

Code: Select all

kb<KB-number>

I do not recomment you to use the second way, because this will permanently prevent wsusou from downloading those updates, it will also delete them from your repository.

Hi aker,
thanks will give that a try.

If your target systems have the latest servicepacks already installed, you could use the update generator to download updates without servicepacks so the ISO files should only contain updates released after the latest servicepacks. Should be less work than to manually exclude all the stuff you don't need (except maybe newer dotnet or IE versions you don't want).
