You can perform a static installation of the JRE if you want the Java Auto Update feature to leave that JRE installed during a Java update.
To perform a static installation of the JRE, specify the command-line option or the configuration file option STATIC=1. The Java Auto Update feature will leave that JRE installed during a Java update.
A later version of the same JRE family will be installed in a separate directory. This mode ensures that vendors, who require a specific version of the JRE for their product, can be certain that the JRE will not be overwritten by a newer version.
The default installation directory of a static JRE is C:\Program Files (x86)\Java\jren (for 32-bit versions) or C:\Program Files\Java\jren (for 64-bit versions), where n is the full Java SE release and update number (for example, n = 1.9.0_20 for release 9 update 20).
