:: Purpose: 1. Nuke ALL versions of JavaFX and the Java Runtime, series 3 through 8, 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
:: Latest version is always here: http://www.reddit.com/r/usefulscripts/comments/1i6kyy/batch_java_runtime_nuker_purge_all_versions_of/
:: additional thanks to:
:: - reddit.com/user/sdjason : JRE reinstall functionality; selective process killing; et al
:: - reddit.com/user/MrYiff : bug fix related to OS_VERSION variable
:: - reddit.com/user/cannibalkitteh : additional registry & file cleaning locations
:: - forums.oracle.com/people/mattmn : a lot of stuff from his Java removal script
:: History: 1.6.3 * IMPROVEMENT: Added pushd command to prep section to ensure we can run the script from a network drive
:: 1.6.2 * IMPROVEMENT: Added /salvagerepository and /resyncperf flags to WMIC winmgmt.exe repair section
:: 1.6.1 * IMPROVEMENT: Added deletion of Java Update directory in C:\Program Files\Common Files\Java\Java Update\
:: 1.6.0 + FEATURE: Added code blocks to catch and remove JRE 8 x86 and x64
:: * IMPROVEMENT: Added Opera browser to list of running exe's to look for prior to performing any action
:: * IMPROVEMENT: Added 2>NUL flags to suppress error output when running the usually-unnecessary official Oracle uninstallers
:: / MISC: Changed example JRE reinstaller variable flags to match up with JRE8-series flags
:: 1.5.1 * IMPROVEMENT: Reworked CUR_DATE variable to handle more than one Date/Time format
:: Can now handle ISO standard dates (yyyy-mm-dd) and Windows default dates (e.g. "Fri 01/24/2014")
:: 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
:: / FIX: Fixed empty OS_VERSION variable on Vista/7/2008/8/2012 (MrYiff)
:: 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
:: 1.3 + FEATURE: Added variables to reinstall Java after cleanup (off by default) (sdjason)
:: + FILE CLEANUP: Added C:\Users*\AppData\LocalLow\Sun\Java\jre* (cannibalkitteh)
:: + FILE CLEANUP: Added C:\Users*\AppData\LocalLow\Sun\Java\AU (cannibalkitteh)
:: 1.2 + COMMENTS: Improved a lot of commenting
:: + UNINSTALLER: Added WMIC wildcard-matching to catch all JRE GUIDs, including future revisions
:: + FILE CLEANUP: Major overhaul to section (mattm)
:: + REGISTRY: Added additional locations: (cannibalkitteh)
:: - HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall
:: - HKLM\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall
:: + PREP: Added Chrome to the list of browsers to kill before starting
:: + PREP: Added /T flag (terminate child processes) to all browser and Java kill lines
:: * LOGGING: Minor improvements
:: 1.1 + Overhaul of functionality and logging
:: 1.0 Initial write
