Note: As of April 8, 2014 Microsoft stopped supporting Windows XP and therefore it is no longer an officially supported platform. Users may still continue to use Java 7 updates on Windows XP at their own risk, but support will only be provided against Microsoft Windows releases Windows Vista or later.
