If you deploy Windows Updates with SCCM go:

Software Library - Operating System - Operating System Images select image you would like to offline update. Right click on it and select Schedule Update and select all updates.

You will need to configure Software Update point first, install WSUS and deploy updates with SCCM before offline servicing becomes available.

Is it possible to open the main image and do online update?
Mike TLeading EngineerCommented:

The answer to your question "can I open the main image and do online update" is yes, you can, using the DISM command with /add-package.

However if you have SCCM 2012 R2, then they already this feature built into the product. You need to enable the role Software Update Point and then configure updates appropriately.

If you really, really want to use DISM then someone has a PowerShell script method, here:

Updates are great once you've set it up but there's a bit of work to do first and you have to be careful with the configuration. The key acronyms are SUP and WSUS which work together. The trick is not to meddle with WSUS, because ConfigMgr controls everything.

My rough overview is:

      1) Install WSUS
        2) Enable SUP role
      3) Sync SCCM to WSUS
      4) Download all patches you want = Provision
      5) Deploy the patches
            a. Manually push - select one or more patches and click "Deploy"
            b. Create a rule (ADR) to automatically filter patches, create a software update group (SUG) and push
For the install you will need to follow the steps below:

A very good walkthrough is on the Windows-noob site, here:
