Add language packs to a Windows 10 multi-session image

Άρθρο
04/24/2023

Azure Virtual Desktop is a service that your users can deploy anytime, anywhere. That's why it's important that your users be able to customize which language their Windows 10 Enterprise multi-session image displays.

There are two ways you can accommodate the language needs of your users:

Build dedicated host pools with a customized image for each language.
Have users with different language and localization requirements in the same host pool, but customize their images to ensure they can select whichever language they need.

The latter method is a lot more efficient and cost-effective. However, it's up to you to decide which method best suits your needs. This article will show you how to customize languages for your images.

Prerequisites

You need the following things to customize your Windows 10 Enterprise multi-session images to add multiple languages:

An Azure virtual machine (VM) with a supported version of Windows 10 Enterprise multi-session.
The Language ISO, Feature on Demand (FOD) Disk 1, and Inbox Apps ISO of the OS version the image uses. You can download them here:
- Language ISO:
  - Windows 10 Language Pack ISO (version 2004 or later)
- FOD Disk 1 ISO:
  - Windows 10 FOD Disk 1 ISO (version 2004 or later)
- Inbox Apps ISO:
  - Windows 10 Inbox Apps ISO (version 21H1 or later)
- If you use Local Experience Pack (LXP) ISO files to localize your images, you'll also need to download the appropriate LXP ISO for the best language experience. Use the information in Adding languages in Windows 10: Known issues to figure out which of the following LXP ISOs is right for you:
An Azure Files Share or a file share on a Windows File Server Virtual Machine

Note

The file share (repository) must be accessible from the Azure VM you plan to use to create the custom image.

Create a content repository for language packages and features on demand

To create the content repository for language packages and FODs and a repository for the Inbox Apps packages:

On an Azure VM, download the Windows 10 Multi-Language ISO, FODs, and Inbox Apps for Windows 10 Enterprise multi-session, version 1903/1909, and 2004 images from the links in Prerequisites.
Open and mount the ISO files on the VM.
Go to the language pack ISO and copy the content from the LocalExperiencePacks and x64\langpacks folders, then paste the content into the file share.
Go to the FOD ISO file, copy all of its content, then paste it into the file share.
Go to the amd64fre folder on the Inbox Apps ISO and copy the content in the repository for the inbox apps that you've prepared.

Note

If you're working with limited storage, only copy the files for the languages you know your users need. You can tell the files apart by looking at the language codes in their file names. For example, the French file has the code "fr-FR" in its name. For a complete list of language codes for all available languages, see Available language packs for Windows.

Important

Some languages require additional fonts included in satellite packages that follow different naming conventions. For example, Japanese font file names include “Jpan."
Set the permissions on the language content repository share so that you have read access from the VM you'll use to build the custom image.

Create a custom Windows 10 Enterprise multi-session image manually

To create a custom Windows 10 Enterprise multi-session image manually:

Deploy an Azure VM, then go to the Azure Gallery and select the current version of Windows 10 Enterprise multi-session you're using.
After you've deployed the VM, connect to it using RDP as a local admin.
Make sure your VM has all the latest Windows Updates. Download the updates and restart the VM, if necessary.

Important

After you install a language pack, you have to reinstall the latest cumulative update that is installed on your image. If you do not reinstall the latest cumulative update, you may encounter errors. If the latest cumulative update is already installed, Windows Update does not offer it again; you have to manually reinstall it. For more information, see Languages overview.
Connect to the language package, FOD, and Inbox Apps file share repository and mount it to a letter drive (for example, drive E).

Create a custom Windows 10 Enterprise multi-session image automatically

If you'd rather install languages through an automated process, you can set up a script in PowerShell. You can use the following script sample to install the Spanish (Spain), French (France), and Chinese (PRC) language packs and satellite packages for Windows 10 Enterprise multi-session, version 2004. The script integrates the language interface pack and all necessary satellite packages into the image. However, you can also modify this script to install other languages. Just make sure to run the script from an elevated PowerShell session, or else it won't work.

$LanguageList = Get-WinUserLanguageList
$LanguageList.Add("zh-cn")
Set-WinUserLanguageList $LanguageList -force

The script might take a while depending on the number of languages you need to install.

Once the script is finished running, check to make sure the language packs installed correctly by going to Start > Settings > Time & Language > Language. If the language files are there, you're all set.

After you've added additional languages to the Windows image, the inbox apps are also required to be updated to support the added languages. This can be done by refreshing the pre-installed apps with the content from the inbox apps ISO. To perform this refresh in an environment where the VM doesn't have internet access, you can use the following PowerShell script template to automate the process and update only installed versions of inbox apps.

#########################################
## Update Inbox Apps for Multi Language##
#########################################
##Set Inbox App Package Content Stores##
[string] $AppsContent = "F:\"

##Update installed Inbox Store Apps##
foreach ($App in (Get-AppxProvisionedPackage -Online)) {
	$AppPath = $AppsContent + $App.DisplayName + '_' + $App.PublisherId
	Write-Host "Handling $AppPath"
	$licFile = Get-Item $AppPath*.xml
	if ($licFile.Count) {
		$lic = $true
		$licFilePath = $licFile.FullName
	} else {
		$lic = $false
	}
	$appxFile = Get-Item $AppPath*.appx*
	if ($appxFile.Count) {
		$appxFilePath = $appxFile.FullName
		if ($lic) {
			Add-AppxProvisionedPackage -Online -PackagePath $appxFilePath -LicensePath $licFilePath 
		} else {
			Add-AppxProvisionedPackage -Online -PackagePath $appxFilePath -skiplicense
		}
	}
}

Important

The inbox apps included in the ISO aren't the latest versions of the pre-installed Windows apps. To get the latest version of all apps, you need to update the apps using the Windows Store App and perform an manual search for updates after you've installed the additional languages.

When you're done, make sure to disconnect the share.

Finish customizing your image

After you've installed the language packs, you can install any other software you want to add to your customized image.

Once you're finished customizing your image, you'll need to run the system preparation tool (sysprep).

To run sysprep:

Open an elevated command prompt and run the following command to generalize the image:
```
C:\Windows\System32\Sysprep\sysprep.exe /oobe /generalize /shutdown
```
Stop the VM, then capture it in a managed image by following the instructions in Create a managed image of a generalized VM in Azure.
You can now use the customized image to deploy an Azure Virtual Desktop host pool. To learn how to deploy a host pool, see Tutorial: Create a host pool with the Azure portal.

Enable languages in Windows settings app

Finally, after you deploy the host pool, you'll need to add the language to each user's language list so they can select their preferred language in the Settings menu.

To ensure your users can select the languages you installed, sign in as the user, then run the following PowerShell cmdlet to add the installed language packs to the Languages menu. You can also set up this script as an automated task or logon script that activates when the user signs in to their session.

$LanguageList = Get-WinUserLanguageList
$LanguageList.Add("es-es")
$LanguageList.Add("fr-fr")
$LanguageList.Add("zh-cn")
Set-WinUserLanguageList $LanguageList -force

After a user changes their language settings, they'll need to sign out of their Azure Virtual Desktop session and sign in again for the changes to take effect.
