Java -version shows old version of java

I have JDK 1.7_51 and JRE 1.7.79 update. My JAVA_HOME is set to C:\Program Files\Java\jdk1.7.0_51 and JRE_HOME is set to C:\Program Files\Java\jre7(update 79) and PATH points to JDK 1.7_51/bin.

Why does the java -version doesn't point to the java 7 79 update? it points java 7 update 51. It should ideally point to the JRE update 79.

For Windows 10: 1) Open Command prompt

2) Type "where java" - Check all paths that are mentioned in the output

3) Go to environment variables -> PATH variable -> Edit -> Ensure that the the version you want to point to is in the list above all other paths.

4) Close the existing terminal, and open a new command prompt.

5) Type "where java" - Check all paths that are mentioned in the output, now your mentioned version path has to be the first in the output.

Try changing your %JAVA_HOME% to the new installation directory and make all attempts to uninstall all previous java installations.

If you're unsure of how to do this, search for "Edit system environment variables" and that's where you'll find environment variables.

You have to put the correct java Path in first place in you PATH variable environment, java es trying to execute the java from c:\windows\system32 first.

When you type in command prompt java it searches the PATH env variable and the first result it hits - returns. Since you pointed the PATH to JDK 1.7_51 - that's what you're getting.

JAVA_HOME environment variable is defined as an agreed protocol for applications that uses Java. It does not apply when you type in command prompt java -version (or java + any other switch).
