Hi,
Question was changing the install system language in 7 not the user interface language.
Changing only the UI language pack may not be sufficient as some installed apps base their language interface on system language and not UI language.
Any idea of how this can be done ?
thanks in advance
Hi Stephane
There is no real 'system language' in Windows 7. Starting with Windows Vista, all of the code binaries that make up the operating system are Language-neutral.
Before distribution a Base (Primary) Language is applied using a MUI Language Pack. This base language defines the language for that version of Windows 7.
Any programs or applications that are installed must be available in the base language or they cannot be translated.
Windows 7 is distributed in 35 base languages. To change the base language you can only use another MUI language pack which will only work on the Ultimate or Enterprise version.
You can apply a freely available LIP (Language Interface Pack) to any edition of Windows 7, as long as the proper base language is installed. A LIP applies a partial translation of the components of Windows 7.
