About this tag
This tag collects WindowsForum.com guidance on configuring windows environment variables for development tools and command-line workflows. The current discussion centers on installing Microsoft OpenJDK 21 with WinGet on Windows 11 and Windows 10 version 1809 or later, then setting JAVA_HOME to the JDK root folder and adding %JAVA_HOME%\bin to the Path variable.

The material suits readers who need practical, step-by-step environment variable setup and validation.
