Disable full screen system wide on OS X 10.9.5

I am using Mac OS X 10.9.5. Having Full Screen at the right end of the each window. How can i disable it? I have tried th below workarounds to fix this but nothing worked out. I listed one of the workaround below. Terminal **Type :** $ defaults write NSGlobalDomain NSAutomaticWindowAnimationsEnabled -bool NO **Hit enter** Close all applications before you do this to make sure the setting propagates. Any app running when you make this change will need to be restarted for the changes to take effect. This is also i got from this forum. What can I do to disable full screen windows?
