'# SCRIPT NAME: jdkManager.vbs
'#
'# DESCRIPTION:
'# VBScript (WMI,WScript) Utility with Command Line Interface. Enables to view all
'# installed JDK/JRE versions [32bit/64bit]. Easily view and re-point Env Variables.
'#
'# NOTES:
'# 32bit Location - HKLM:\SOFTWARE\WOW6432Node\Microsoft\Windows\CurrentVersion\Uninstall\'
'# 64bit Location - HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\
'# Registry Enumeration uses 'WMI' & Environment Variables functions use 'WScript.Shell'
'# Since the WSH Shell has no Enumeration functionality, you cannot use the WSH Shell
'# object to parse Registry "tree" unless you know the exact name of every subkey.
'# The WMI Classes used are 'StdRegProv' and 'Wim32_Environment'
'# Do not use WMI Class 'Win32_Product' as this class has known issues documented (KBArticle 794524)
