Disable Ease of Access in windows 7

Finally found a command that will completely disable Ease of Access in windows 7. On the command line, run

cacls %windir%\system32\utilman.exe /C /D Everyone

and hit Y when prompted. This will remove the functionality behind that stupid button on the windows screen and will stop the stupid ease of access dialog from popping up when you're typing in your password to the login page.
