Something that used to be quite simple, is now not so simple. With the advent of Cortana, the English (Australia) Language pack is now no longer included in the base Windows 10 ISO. This does make some sense given the large number of languages that Windows 10 now supports with Cortana in mind.
By default if you deploy Windows 10 Enterprise using Configuration Manager with an Unattend.xml file specifying en-AU as per this example:
You end up with Australia as your region but with English (US) as your default display language.
You also do not have English (Australia) as your Speech Language with no Australian Text-to-speech voice options.
In order to fix this we need to add a Language Pack as well as some additional cabinet files from the relevant Windows 10 Features on Demand ISO available though VLSC.
To be clear – if your deploying Windows 10 1607 x64 Enterprise – you will need to download the Windows 10 1607 x64 Enterprise Language Pack ISO and the Windows 10 Features on Demand ISO as there are individual ISO’s per Windows 10 release.
You will notice that there is no en-AU language pack cab file. This is because the English (Australia) display language is a part of the en-GB cab file. There are specific en-AU Text-to-speech and Speech cab files though which should be added for Cortana functionality.
- Copy the following cab file from the extracted Windows 10 Language Pack ISO to a source folder on your ConfigMgr source packages share.
- Copy the following cab files from the extracted Windows 10 Features on Demand ISO to the same source folder
- Rename the files to the following, this will ensure they install in the correct order:
- Create a ConfigMgr Package i.e. Windows 10 1607 en-AU Language Pack and Distribute to your DP’s
- In your Task Sequence add a Run Command Line step after the Setup Windows and ConfigMgr Step, this will call DISM and add the cabinet files
- Once the deployment is finished, logon and open the Settings App. Open Time & Language and you should see under Region & language that English (Australia) is present with “Language Pack Installed”. If you open the Speech option, you should see English (Australia) as the spoken language.
