System Locale being ignored

[clareq]

I'm implementing SCCM 2012, and working on the OSD. I have a very simple unattend.xml which should set the language options to English(UK). Location seems to be going in OK, but system locale is still English (US)

 

The unattend.xml is:

   
       
           en-GB
           en-GB
           en-GB
       
       
           false
           false
       
   
   

 

Any ideas?

What version of Windows are you using? If Win7, there is no en-GB locale. The first version of Windows that came with one was Windows 8.

Windows 7. i can set the locale to UK in control panel once a machine has deployed. Is there any way to set it during deployment, or by GPO. Failing that I need to find a way to globally set Office 2013 to use UK english, because it's following the locale at the moment.
