Set PATH for JDK 7 on Windows 8

You can run the JDK without setting the PATH environment variable, or you can optionally set it so that you can conveniently run the JDK executable files (javac.exe, java.exe, javadoc.exe, and so forth) from any directory without having to type the full path of the command.

To setup PATH in Windows 8:
Run Control Panel in Windows 8's Metro UI


Click More Settings in Control... on the left.


Search "Environment Variables" in Control Panel, and click "Edit the system environment variables".


Click on "Environment Variables..."


Scroll down to highligh and edit path items.


My full path of the bin folder of the JDK is:
C:\Program Files\Java\jdk1.7.0_02\bin

So add ";C:\Program Files\Java\jdk1.7.0_02\bin" in the path string.


Click OK... to finish.

Re-open Windows 8's "cmd" window, now i can start java and javac in anywhere.

    1. no, some programs that use the path variable wont work though and you will have to look up their paths and add them in again. nothing irreparable. i did it a few times myself

  10. I have done the instructions but neither "java" or "javac" work. I just get told it's not recognised as an internal or external command, operable program or batch file.
    Thanks in advance.

    1. 1. open command promt.
      2. with cd command go to your java directory
      3. then try java or javac.
      4. If it is not working then something problem with your installation else try it once again as said in the above article.

  11. It's more easier to access the System panel with the shortcut (Windows Key) + Pause with the Desktop Mode.

    Then you go directly to the Advanced Tab
