Installing the JDK Configuration environment variable Java_home does not work

Today reinstall the system, need to install JDK, configure environment variables, so first configure Java_home D:\Program files\java\jdk1.8.0_144,

The path path is then configured, but the CMD to DOS command line input javac and Java commands do not work, so configuring the absolute path of path is OK, but

Still want to know why, so in csdn above found the answer, originally I put java_home configured to the user variable, and path is in the system variable, so

The problem is solved by configuring the Java_home to a system variable by referencing the Java_home.
