there is one more file named cmd.exe you have to rename it to sethc.exe.and have to rename the sethc.exe to cmd.exe but you will not be able to rename both the file because it will ask  you to provide administrator permission to rename both the files.to get the permission for both the files you have to follow the steps below:-Right Click on the file> Properties> Security


















It does not have full control.Click on Advanced>Owner
