Apply language settings to all users with PowerShell

Hello,

I wish to apply the en-AU and ja-JP input methods to all user accounts through PowerShell. The international module only affects the current user.

This command does what i want, but only affects the current user, is there a way i can apply the language settings i want to all user accounts through PowerShell?

Set-WinUserLanguageList -LanguageList "en-AU","ja-JP"
