==Java Runtime Environment (JRE) 6 Update 1920==
"Java Quick Starter" is described as a prefetching service that should make java applications start faster. But it has a drawback: it must be killed before uninstallation or installation fails, and uninstallation via msiexec does not seem to be smart enough to do this.
This requires the Windows Offline installation package available from Sun. Note that a particular Java family install package does not remove already installed versions of another Java family, so JRE 1.5 and JRE 1.6 can coexist; all older 1.6 update versions (1.6.0 up to 1.6.0 Update 11but not including the most recent version) are tried to be removed uninstalled by the following packaging (note that the update version seems to be no more reflected in the last number in the Uninstall ID).
Actually, with Update 10 and later Sun has introduced as default the so called "patch in place" update mechanism (see: http://java.sun.com/javase/6/docs/technotes/guides/jweb/otherFeatures/jre_install.html) which automatically removes the previous version of the same Java family (unless you turned off patch-in-place using the installer). So the line that tries to remove a previously installed Update 10 (msiexec /qn /x {26A24AE4-039D-4CA4-87B4-2F83216010FF}) is not strictly necessary (if you installed a 'Family JRE' and not a 'Static JRE').
==== JRE without Java Quick Starter on 32-bit hosts ====
The following installs JRE Update 19 20 and then removes the "Java Quick Starter" service; if you want to keep "Java Quick Starter" service then just remove the line with "jqs.exe -unregister", but remeber to stop/kill JQS before uninstallation.
