How to use Windows 10 Upgrade Task Sequence to install Multiple Languages

Microsoft encourages Windows users to upgrade their experience to the latest version of the OS – Windows 10. However, the process isn’t always smooth and may face hurdles, not anticipated by the customer. This can be noticed especially when Standard Desktop Client has Multiple Language Packs installed. Fortunately, Microsoft offers an Upgrade Task Sequence, a built-in System Center Configuration Manager as a solution for this problem. It offers all in place Upgrade options if the OS UI Language matches the Windows Setup Media Language used. This method does not harm users’ files in any way and leaves them all intact.

Having said that, if you add language packs using DISM, the licensing requirements of how many that, language packs can run on the Windows edition will not be verified. The result, multiple language packs which are not offered by the provider, will be removed from the computer after a period. It is, therefore, necessary to find which Language Packs are currently installed on the device running Upgrade Task.

This can be verified easily via the following command line

dism.exe /Online /Get-Intl

Selecting English (en-US) which is different from the default German language on the sample device will provide us with the following screen,

This can be solved by employing the following method:

run dism.exe /image:d:\ /set-uilang:en-us

against your Windows Installation (Drive where your Windows 7 is installed)

Restart your Device.

As seen in the image below, we can find that default system UI language has now been set to English (en-US).

Running Windows Setup again on the same device will let you keep personal files and settings in original form.

This MSDN page features all the command-line options listed for Windows Setup. Beginning with Windows 10, version 1607, you can use a setupconfig file as an alternative to passing parameters to Windows Setup on a command line.

As an alternative to the above method, you can use an automated solution – it requires 2 PowerShell Scripts plus some Condition based Task Sequence Steps to get work done.
