Disable Java Automatic Updates: Change Java Update options.

Create java_check_update.ps1 PowerShell script with following content:

$currVer = Get-ItemProperty "hklm:\SOFTWARE\Wow6432Node\JavaSoft\Java Runtime Environment" -name "CurrentVersion"

if (!$currVer.'CurrentVersion') {

$famVerStr = ('Java' + $currVer.'CurrentVersion'.Split(".")[1] + 'FamilyVersion')
$famVer = Get-ItemProperty "hklm:\SOFTWARE\Wow6432Node\JavaSoft\Java Runtime Environment" -name $famVerStr

if (!$famVer.$famVerStr) {

$java_version = $famVer.$famVerStr

$url = "http://javadl-esd.sun.com/update/" + $currVer.'CurrentVersion' + ".0/map-" + $currVer.'CurrentVersion' + ".0.xml"

$c = New-Object System.Net.WebClient
$xml = $c.DownloadString($url)

$p = [xml]$xml
$n = $p.SelectSingleNode('java-update-map/mapping[version="' + $java_version + '"]')

if ($n) {
    #update available
    cmd.exe /c "C:\Program Files (x86)\Common Files\Java\Java Update\jucheck.exe"

Create java_check_update.vbs VBScript with following content:

Set oShell = CreateObject("WScript.Shell")
oShell.Run "powershell.exe -ExecutionPolicy Bypass -WindowStyle Hidden -File ""PATH_TO_POWERSHELL_SCRIPT""", 0

PATH_TO_POWERSHELL_SCRIPT for example: D:\Scripts\java_check_update.ps1

Add new task in Task Scheduler to run script java_check_update.vbs (full path to file) every day, week or month.


You can also use this program auto java updater. Schedule it and let it run in the background and it will do everything automaticly.
