For browser support as well as Linux, Solaris and Mac OS X, see Oracle JDK 9 and JRE 9 Certified System Configurations Contents. Java Version 9 is not compatible with Windows XP or Windows Vista.
Oracle does not plan to migrate desktops from Java 8 to Java 9 through the auto update feature. Therefore, it is strongly recommended that you uninstall JRE 8 prior to updating.
- UNcheck any pre-checked toolbar and/or software options presented with the update. They are not part of the software update and are completely optional.
- Verify your version: http://www.java.com/...ad/testjava.jsp.
Note: The Java version verification page will only work if your browser has NPAPI support. In that case, to check the version, open a cmd window and enter the following (note the space following Java): java -version
