[ltsb, 1607] Slip-streaming updates in to WIM

[kennysarmy]

Since rolling out Windows 10 I've been able to take the WIM file from our WDS/MDT setup and slipstream in any major updates to save time when imaging PC's.

 

The process has been:

 

Take a backup of the WIM file from the MDT server (DeploymentShare\Operating Systems\etc)

 

Copy the WIM file from the MDT server rename wim.wim

 

Download any recent updates from Microsoft Update Catalog

 

Then run the following commands to slipstream in any new updates

 

dism /mount-wim /wimfile:D:WIM\wim.wim /mountdir:D:WIMTEMP /index:1

 

dism /image:D:WIMTEMP /Add-Package /PackagePath:D:updates

 

dism /Unmount-Wim /MountDir:d:\WIMTEMP /commit

 

Copy the wim file back to MDT.

 

 

This week I carried out this process, attempting to slip-stream in the following file : windows10.0-kb4530689-x64_a7cbdbcf320f1c56dace2424dedd4d468cd46d3d.msu

This is the 2019-12 Cumulative Update!

 

The DISM process completes without error and the WIM file size grows.

 

However, when I re-image a test and subsequent PC's they all still find the 2019-12 Cumulative Update and re-install it again.

 

Can anyone advise what might be going wrong here?

How can an update be installed AND ALSO be required???

Are you missing the latest SSU (Servicing Stack Update)?

 

Sometimes you have to apply the SSU first before the updates apply correctly.

 

What happens if you use a fresh wim with OSDBuilder or WimWitch to apply the updates?

Yes, KB4520724 from the screenshot also gets successfully installed.

 

I'm going to try slip streaming in from another PC running a different version of the ADK.

Same issue on another PC with a different ADK installed.

 

Updated the WIM, copied back to the MDT, imaged a PC, then it finds the 2019-12 CU again from our WSUS

 

Not sure what else to try now...

 

Perhaps installing the SSU, unmounting the image and going through the process again to install the CU.

 

Otherwise I'm stuck

Maybe wait until next months updates and try that one?
