As we've been promising for quite awhile, there is now a single Windows installer. Depending on the language you choose in installation, it will install the necessary version of Java (with or without support for international characters). The new installer installs Java 1.5 if it detects they have Java 1.4.0 or below.

There is no such thing as, nor a need for the international installer now.

I'm not sure what you mean by a "standalone windows installer". The installer for windows is all you'll ever need.
