Just set the path variable to JDK bin in environment variables.

Variable Name : PATH 
Variable Value : C:\Program Files\Java\jdk1.8.0_31\bin

But the best practice is to set JAVA_HOME and PATH as follow.

Variable Name : JAVA_HOME
Variable Value : C:\Program Files\Java\jdk1.8.0_31

Variable Name : PATH 
Variable Value : %JAVA_HOME%\bin

I need help finding the location of my java_home/bin

• "Start" > "Control Panel" > "Java".

• Select "Java" tab.

  

• Click "View"

• Look in the "Path" column for version of the JRE you have installed.

  

In the above example the "Path" contains:

C:\apps\jdk\jre\bin\javaw.exe

JAVA_HOME should point to the root directory of the Java installation, so in this case:

C:\apps\jdk

And the PATH should contain JAVA_HOME\bin, in this case:

C:\apps\jdk\bin

From a command prompt we can set these values using the following commands:

setx JAVA_HOME C:\apps\jdk
setx PATH C:\apps\jdk\bin;%PATH%

Notes:

• Modify the above commands as appropriate for your Java installation.
• These are System not User environment variables.

See Installing the JDK Software and Setting JAVA_HOME and PATH and CLASSPATH for more information.

I need to setup a task on a few machines with apps that require the correct Java version path in their environment variables.

This was suggested, but requires some work apparently:

Remove-PathFolders -Folders “\Java\jdk” -EnvironmentVariableTarget $([System.EnvironmentVariableTarget]::Machine) $jdkDp = (Get-ChildItem -Path “C:\Program Files (x86)\Java\jdk*” | Sort-Object name | Select-Object -Last 1).FullName Add-PathFolders -Folders $($jdkDp + "\bin") -EnvironmentVariableTarget $([System.EnvironmentVariableTarget]::Machine) Get-PathFolders -EnvironmentVariableTarget $([System.EnvironmentVariableTarget]::Machine)
