Auto-update and update through Java Control Panel of JRE 6 will replace JRE 6 with JRE 7

Since JRE 6 has reached its End of Public Updates Oracle is taking steps to protect consumer desktops. We will not leave a version of Java installed for which we no longer provide security updates .

In order to do so, when updating from JRE 6, the update mechanism will not only install the latest version of JRE 7 but will also remove the highest version of JRE 6 on the system. This change will happen when the system is updated via the auto-update mechanism or by checking for updates directly from the Java Control Panel.

Users who need to keep a version of JRE 6 in their systems can do so by manually installing the latest version of JRE 7 rather than relying on auto-update or updates through the Java Control Panel.

If JRE 6 has already been removed from a system, but the user would like to restore it, earlier versions of Java can be accessed from the Java Archive.

Note that Oracle strongly recommends leaving only up-to-date versions of the JRE on desktops. Retaining an older version of the JRE in your systems should only be done by expert users or enterprise administrators with a need for those earlier versions and an understanding of the associated risks.
