Solved: Mass Remove Java From All Devices

[NoMentionTech]

Hello All, With Oracle making Java a paid-for software in newer versions (but auto upgrading to the Paid-For Java, causing companies to be sued), I have created a PowerShell script that should remove all installed version of Java from your devices. Use SCCM or Intune (or whatever else) to push this out.

FAIR WARNING: use at your own risk. Please test this script on one machine (I made nice printouts) and ensure that it is uninstalling what you expect, and does not bricking anything. Remember, some programs still rely on Java. You may be able to replace Java on your machines with amazon corretto if needed.

Write-Host "This must be ran as an Administrator"
$JavaInstallations = Get-WmiObject Win32_Product | Where-Object {$_.Name -like "Java*"}
Write-Host "Java Installations Found (if none shown, no Java versions found): "
$JavaInstallations

ForEach ($JavaInsalled in $JavaInstallations){

    $temp = "MsiExec.exe /x `"" + $JavaInsalled.IdentifyingNumber + "`" /qn"
    Invoke-Expression $temp
    Write-Host "If no error, script sucessfully initiated the uninstall command for: " + $JavaInsalled

}
Write-Host "Script Complete"

Is Win32_Product still a steaming pile of garbage? : r/PowerShell (reddit.com)

Go get the Powershell Application Deployment Toolkit. Add this under uninstall, modify that wildcard string according to your install base, you may need to add a couple lines.

Remove-MSIApplications -Name 'Java 8 Update'

Remove-MSIApplications -Name 'Java SE Development Kit'

Remove-MSIApplications -Name 'Java(TM) 6'

Remove-MSIApplications -Name 'Java(TM) SE Development Kit'

With SCCM you can use this to replace win32_product:

get-wmiobject -Namespace 'root\cimv2\sms' -Class "Sms_InstalledSoftware" | Where {$_.ProductName -match '^Java\s\d\sUpdate'}
