Hello, I am using Windows 7 Professional. After installing my operating system, the CMD worked fine. But after a while, it stopped working properly. I cannot execute any Windows commands. Even when I type "ping," it says that "ping is not recognized as an internal or external command, operable program or batch file." I don't know why this is happening. It doesn't recognize "ipconfig," "getmac," and many others. Please help me.

Configuration: Windows 7 / Safari 535.19

My Path does not contain this value, but rather the path of the JDK. What should I do? Should I create another Path or what? My machine requires the JDK. What should I do?

I deleted the JDK path to put the Windows one.
