How many language groups are there?
There are seventeen language groups including the Western Europe and United States language group, which always installs as the default for Windows 2000 and cannot be removed. The seventeen groups are:
Arabic; Armenian; Baltic; Central Europe; Cyrillic; Georgian; Greek; Hebrew; Indic; Japanese; Korean; Simplified Chinese; Thai; Traditional Chinese; Turkish; Vietnamese; and Western Europe and United States.
Any number and combination of language groups can be installed on any Windows 2000 version. Our List of Language Group IDs gives the ID values of each language group for use in unattended mode installations of Windows 2000 and the Windows 2000 MultiLanguage Version.
How to add language groups in Windows 2000?
