Batch files, to my knowledge, can never be blocked
Yes they can stop you from writing one, but they can never block one from running
By using command.com and saving it as a batch file is an excellent way of getting access to a whole system even if it is restricted
If they blocked notepad so that they believe that you can't create a batch file, just go into internet explorer and go view source in the view menu and you got yourself a notepad
Or if you want, you can choose any text editor, but make sure that you delete the batch file later to give the challenge to other people
Command prompt gives you virtually access to the whole system, you can search the directories, save files on it, format the computer or just wipe out certain folders
And remember, with command prompt, the force is in you !
Haha ... that was lame sry
