Internet Explorer 8 is now available in 18 additional languages. This now takes it to a total of 43 languages.
If you had already installed Internet Explorer 8 in English and you had an underlying Windows Vista or Windows Server 2008 operating system in any of the above languages, you can experience localized Internet Explorer 8 by installing the Internet Explorer 8 Language pack that matches your operating system language(s).
Users who have more than one Language pack installed on their machine could benefit from installing Language packs as well.
Furthermore, Internet Explorer 8 will be made available shortly in an additional 20 languages.
