Hi
Yes this is Windows 7 with SCCM 2007 R2 Sp2 and MDT 2010, but I´dont use mdt, only to get the script in to sccm servern.
I mounted the wim file with DISM and added the sv-se folder. In the cs file´everything is pointed to use swedish.
Then when I´m deploying windows 7 need to chose swedish or english language.
