There are 2 places where you might find the product code:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Installer\UserData\S-1-5-18\Products\4EA42A62D9304AC4784BF238120662FF\InstallProperties

or

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall

You should be able to find the uninstall string from the key UninstallString; something like: MsiExec.exe /X{26A24AE4-039D-4CA4-87B4-2F83216026FF}

You should be able to use regular Windows Command Line Tool to uninstall the software as Windows sees it as a MSI style install software. If you want to get rid of All Java named programs you can always do the following in a batch file:

wmic product where "name like 'Java%%'" call uninstall

I’ve used it in multiple places I’ve worked and it’s been great. That being said, if you want to uninstall other software that doesn’t seem to work with wmic, you can look in the Windows Registry and most of the installed program will state what you need to do to uninstall and in some cases even give you the command to silently uninstall.

HKLM\Software\Microsoft\Windows\CurrentVersion\Uninstall\

and

HKLM\Software\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall\

We had a MAC computer that we wanted to uninstall JAVA from. We ran the following commands:
sudo rm -fr /Library/Internet\ Plug-Ins/JavaAppletPlugin.plugin
sudo rm -fr /Library/PreferencePanes/JavaControlPanel.prefPane
sudo rm -fr ~/Library/Application\ Support/Oracle/Java

and

rm -r ~/“Library/Application Support/Oracle/Java”

The first 3 commands were taken from this article:
(https://www.java.com/en/uninstall/uninstall_instructions.html#macOS)

And the 4th command was taken from this article:
(https://www.java.com/en/download/help/deployment_cache.html)

However, our RMM claims this computer still has JAVA. So, do you think these commands would have indeed uninstalled JAVA? Is our RMM likely incorrect?

Thank you.
