I spent a lot of time to find out how to check what’s language version of installed windows 2003. And it was quite difficult to find solution. Anyway you can get this information in system registry:

1. Run registry editor: ”regedit”

2. Go to [HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlNlsLanguage]

3. And key “InstallLanguage” describes what’s installation language
