 :: Purpose:       1. Nuke ALL versions of JavaFX and the Java Runtime, series 3 through 7, x86 and x64
 ::                2. Leaves Java Development Kit installations intact
 ::                3. Reinstalls the latest JRE (if you want it to)
 ::                4. Puts the lotion on its skin.
 :: Requirements:  local administrative rights; WMI
 :: Author:        vocatus on reddit.com/r/sysadmin and /r/usefulscripts
 ::                additional thanks to:
 ::                 - reddit.com/user/sdjason         : JRE reinstall functionality; selective process killing; et al

 ::                 - forums.oracle.com/people/mattmn : a lot of stuff from his Java removal script
 :: History:       1.5.0 + FEATURE:      Added ability to choose whether or not to kill running Java processes before executing,
 ::                                      along with a variable to specify an exit code to use                   (sdjason)
 ::                      + FEATURE:      Added ability to selectively reinstall x64 and x86 versions of the JRE (sdjason)
 ::                      * IMPROVEMENT:  Converted JRE 3 uninstaller section to a FOR loop
 ::                      * IMPROVEMENT:  Converted many commands into FOR loops with test cases to check if they should run or not (sdjason)
 ::                      * IMPROVEMENT:  File deletion commands now aren't run if their target doesn't exist.
 ::                                      This should reduce unecessary errors in the console and log.     (sdjason)
 ::                      / FIX:			Fixed incorrect search string in XP version of Java installer cache purge
 ::                1.4.1 / FIX:          Re-enabled "echo off" statement at beginning of script

 ::                1.4   + FEATURE:      Added check to see if we're on Windows XP, to run different code for certain sections
 ::                      + FEATURE:      Added comprehensive WMI repair if it's broken
 ::                      + FEATURE:      Added XP versions of a lot of the code
