A: Since Service Packs and updates for Windows Vista / 7 / Server 2008(R2) are multilingual, there's no 24-language selection table for these platforms, so by default, only the English and German versions of those localized installation packages for IEx, .NET and MSSE will be downloaded.
To have your favorite locale(s) downloaded in addition, you may use the ...\cmd\AddCustomLanguageSupport.cmd script.
For you, it would be ".\cmd\AddCustomLanguageSupport.cmd chs".
To remove the German downloads run .\cmd\RemoveGermanLanguageSupport.cmd.
