The easiest way to install language pack via Intune with PowerShell

The purpose of this blog post is to inform you how to install the language pack on Windows 10 or Windows 11 via Microsoft Intune. In this blog post, I list several different methods and then I will show my preferred ways.

There are several options to install the language pack via Microsoft Intune. When you have to deal with a multilingual environment, it could be hard to install the right language pack via Microsoft Intune. Especially when your users want or need to use Windows in their own language, but your global service desk is English-orientated. Also, not all languages are installed by the vendor, so you have to install the language via Intune. This can be a hard job when the users are all over the world, but I will explain my preferred way how to install the language pack via Intune easily.

Requirements:

Windows 10/11 Pro/Enterprise version 21H1 and later
The latest cumulative update installed
Microsoft Intune license
Intune MDM managed device
Intune Admin or Global Admin Role

Optional requirements:

Windows 10/11 Enterprise E3/E5 Or Microsoft 365 F3/E3/E5 license
Endpoint Analytics

Previously installation possibilities

There were several options available to install the language packs on Windows 10/11

Manual installation via Settings
Manual installation via Microsoft Store
Manual or required installation via Company Portal, Microsoft Store, and PowerShell

Update from Microsoft

Since the 20h2 latest cumulative update, a new PowerShell command is available to install the language pack. I have tested this option, and this is awesome. I have already implemented this setting in multiple Intune environments. Also, I hear al lots of positive feedback in the community about this new method.

There are five PowerShell commands available to get, install, remove, or set the preferred language. It is easy to use, for example, to install a language pack use the following command:

Install-Language nl-NL

The PowerShell commands need to be run as an administrator and ask your users to run a PowerShell command is also not super user-friendly. Later more about this.

What are the new PowerShell commands?

PowerShell commands	Description
Get-InstalledLanguage	Returns information about the installed languages on a device.
Get-SystemPreferredUILanguage	Returns the current System Preferred Language.
Install-Language	Installs a language onto a device.
Set-SystemPreferredUILanguage	Sets the provided language as the System Preferred UI Language.
Uninstall-Language	Uninstalls a language from a device.

Note. Click here for all language pack tag

New installation possibilities

Today we have the below options available as well to install the language packs on Windows 10/11

Manual or required installation via PowerShell (Install-Language)
Required installation via Proactive remediation Script (Install-Language)
Manual or required installation via Company portal, Win32App & PowerShell (Install-Language)

Which option should I use?

As you can see in the above list, there are several ways to install the language pack on Windows 10/11. formerly, I advised my customers to install the language pack manually because installing the language pack via Company Portal does not work properly. The language pack will be installed but will not appears in the list of available language. So, the user needs to run a PowerShell command in the user context. In my opinion not very user-friendly.

Also, I don’t like to tell the users you can install the language pack in the Microsoft store and your application in the Company Portal. I prefer one source of truth, and this is also not user-friendly in my opinion.

Of course, you can download the language pack and add a PowerShell script and wrap those files in a win32 app and distribute via Intune, but the PowerShell command will override the installed language(s) and default language. So, this is also not user-friendly.

So that was the reason why I always recommended installing the languages manually via settings. But now we have the new PowerShell command to install the language pack. This makes it easier to install the language packs.

The new PowerShell command is definitely my new preferred method. But depending on the organization’s preferences, I use the PowerShell, Proactive remediation, or Win32 app method via Intune. I will explain these three options in the sections below.

Hi There,

I have a strange issue, as I am trying to run install-language as a task sequence PowerShell script step. Even tough I can see the language pack management files in the system32 module folder ( I assume it means its installed) and I import the module. When I run the command install-language I receive an error install-language is not recognized. Will the command run as system account or do we need to run it as admin user. Pls guide me further.

  Hi yuva, you can run it as both users, intune runs the scripts via the system account but when I install it from PowerShell it will runs under my admin account.
  
  Which version of windows are you using because there are some specific versions and update required.
  
  Are you using mdt of sccm to install the language pack and in which phase ?

  Hi Dan, did you get any error code in PowerShell? Did you run it as an Administrator?
  Would you please share the total command?
