Hello all I want to remove almost every language, but i need to let Baltic, Cyrillic and Western Europe and US. In winnt.sif [RegionalSettings] label i have settings: [RegionalSettings] LanguageGroup = 3,5,1 Language = 00000427 InputLocale_DefaultUser = 0409:00000409 SystemLocale = 00000427 UserLocale = 00000427 UserLocale_DefaultUser = 00000427 where Language 0x0427 is Lithuanian (Lithuania), LanguageGroup 1 is Western Europe and United States, 3 is Baltic and 5 is Cyrillic But after installing windows on Regional and Language Options i have English (US) on every tab (had to be Lithuania). Where is the error ?
