Windows Embedded Standard 7 adopts same localization model as the Windows 7. Basically, language resources are completely separated from the code, enabling a worldwide binary which doesn’t require localization in all supported language. All localizable resources are packaged in the form of language pack, and Standard 7consists of language neutral image plus language packs.
Users can configure languages through Region and Language control panel applet, which can be launched either via the control panel window or via a command line, for example “rundll32 shell32.dll,Control_RunDLL intl.cpl”. The following can be configured: Switch UI language after installing non en-US language pack and associated font packages; Change locales Change Keyboard and input language; Remove language package via LPKSETUP (or command line tools DISM).
