Windows Updates from WSUS during SCCM OSD

TGH Profile Image 512x512

I’ve recently had a situation where I needed to install Windows Updates as part of the OSD process. However, the updates had to be run directly from the local WSUS server rather than from SCCM built in software updates solution.

To do this, all you need to do is to install and integrate MDT. Once you have done this you will have the option to use the scripts within MDT, the script that we are looking at using for this process is:
  • ZTIWindowsUpdate.wsf
To make this work, you need to add the following steps to your task sequence towards the end of the sequence:
  • Use MDT Package
  • Set Task Sequence Variable
  • Run Command Line
The Use MDT Package speaks for itself, this is to make the MDT toolkit available to the task sequence, then the variable that you need to set in the Set Task Sequence Variable is dependent on your WSUS server, as an example:
Then the command line that you need to run is:
  • cscript.exe “%SCRIPTROOT%ZTIWindowsUpdate.wsf”
This should then install all required updates from your specified WSUS server.
