The command to echo JAVA_HOME in Microsoft PowerShell uses the $env notation. If you need to configure these settings manually, follow these tutorials on how to configure JAVA_HOME or set the Java PATH. Not all Java installers configure these environment variables.

When you setup Java on Windows, change the installation folder and choose to set JAVA_HOME.
