 ## 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.
