How to Update Java On Multiple Machines Simultaneously

As a Systems Administrator, keeping software up to date is rather important for all sorts of reasons. Updating Java is no exception. So what do you do when you see a Java update available and you have 160+ computers to update? Script it of course.


That other system works, but the new system is much more reliable and works on both 32bit and 64 bit systems.

Step 1

Download a Java installer from and place it in a network accessible folder. I also update Notepad++ at the same time since it needs regular updates.

Step 2

Copy the installer to a local folder on each of the servers or computers

psexec @computergroup.txt -u domain\user -p password -n 20 cmd /c copy "\\networkshare\folder\Ninite Java 8 Notepad Installer.exe" c:\scripts

Step 3

Run the installer on all of the servers or computers

psexec @computergroup.txt -u domain\user -p password -n 20 cmd /c  "c:\scripts\Ninite Java 8 Notepad Installer.exe"

My Previous Method

Step 1

Remove older versions of Java
run “MyUninstaller” to get the command line script for removing older versions
MsiExec.exe /X{26A24AE4-039D-4CA4-87B4-2F83217007FF}
MsiExec.exe /X{26A24AE4-039D-4CA4-87B4-2F83216023FF}

I then added the above lines to “java-uninstall.bat”.

Make a C:\scripts directory on all computers on your network.

psexec \\* -u domain\adminuser -p password cmd /c md c:\scripts

Push out java-uninstall.bat to c:\scripts\ folder

psexec \\* -u domain\adminuser -p password cmd /c copy "\\NFS\software\batchfiles\java-uninstall.bat" c:\Scripts

Uninstall Java on all computers

psexec \\* -u domain\adminuser -p password cmd /c c:\Scripts\java-uninstall.bat

Step 2

Download Java offline installer

Create a Java Installer batch file with the following switches. You might want to check these to see if any other switches are needed. Also, specify your own Network File Share.

\\NFS\software\tools\Java\javasetup.exe /s /v" /qn IEXPLORER=1 MOZILLA=1"

Push out java-install.bat to c:\scripts folder

psexec \\* -u domain\adminuser -p password cmd /c copy "\\software\batchfiles\java-install.bat" c:\Scripts

Run the batch java installer.

psexec \\* -u domain\adminuser -p password cmd /c c:\Scripts\java-install.bat

That’s it! Chances are Java will be updated within a few months and this process will need to be repeated. By renaming the java installer, it allows this script to be run whenever Java is updated.
