Setting Language Used in Menu's and dialogues

[hardmandez]

Hi Everyone

I am trying to setup our RIS unattended build to set the default language for menu's and dialogues from the unattend.txt.

I do not want to have to use the guirunonce or cmdlines.txt though as I want the build to be as generic as possible using these methods would require to many different scripts for all the languages. I would like to be able to configure this option in the [RegionalSettings] so all I have is a standard format where only one line section needs to be changed if you know what I mean.

Is there a setting in unattend to set this? Or could I do this in group policies which applies to the workstation?

Thanks
