The following is what we use, works great as a startup script:
on error resume next
dim WshShell
dim RegKey
dim ScriptVerKey
Set WshShell = CreateObject("WScript.Shell")
'checks to see if registry key exists, if it does, the cleanup runs.
RegKey = "HKLM\SOFTWARE\EDU\Cleanup\"
ScriptVerKey = WshShell.RegRead(RegKey & "JAVAOldVer")
if ScriptVerKey <> "1" Then
Cleanup()
Else
WScript.Quit
End If
Sub Cleanup()

JDK and JRE are relocatable. You can move them without any problem. Make sure you point JAVA_HOME or JRE_HOME to the proper folder.
