You have an Azure Virtual Desktop host pool.
You add a French language pack to each session host in the host pool.
Several days later, users report that English displays when they connect to Azure Virtual Desktop.
After an investigation, you discover that the French language pack was removed, and the session hosts reverted to English.
You need to ensure that the French language pack is always available on the session hosts.
What should you do?
