What I'll show you how to do today is to make a message open up when you click on your jump drive from My Computer in windows. You will learn to create (or modify) an autorun.inf in the root of your jump drive and create a batch file to be run when you open your jump drive. I will also show you how to display a message when that batch file opens, and optionally add a command prompt to the end that looks like an innocent blinking underscore. Basically, from here, you can do almost anything on a computer that you can't do because of a limited account.
For rather tech suavey people, step 6 is a short version of the whole instructable.
For rather un-tech suavey people, step 7 includes everything you need, plus a simple file
to install it to your jump drive.
Step 1: Gather Supplies
Get a working jump drive, any size. I'll be using an 8 gig Verbatim jump drive, but really you could do this with a 50 kilobyte jump drive. You will need to be running windows to use it, but any OS can make it. Open up notepad or your OS equivalent. In windows, go to Start-All Programs-Accessories-Notepad .
Also, it might help to have Folder Options under Control Panel set to show hidden files and folders.
