Make sure the file has the .bat suffix. Notepad may have "sneaked" a .txt on the end ...
Other than that there is nothing special you have to do for a batch file to work.
Try adding a couple of PAUSE commands to stop the execution to see what is happening. Just in case there is a error message that you are not seeing because it flashes by so fast.
Try building up your bat file in small increments of a command or two at a time. Always end with a Pause to see what is going on.
