To open a finite number of windows, start a new line and type the following command into your notepad window: start (program name here). In place of the phrase of parentheses, put the name of a program on your computer or its precise file location. This command causes the computer to open a window of the program you specify. For example, start iexplore. exe will open a window of Internet Explorer. Repeat this “start” command as many times as you’d like - your “virus” will open a window for every time you repeat this command. Here are just a few ideas for programs you may want to enter after “start”: iexplore. exe - Internet calc. exe - Calculator notepad. exe - Notepad winword. exe - Microsoft Word (tested with version 2013, may work with other versions) To open an infinite number of windows, first start a new line and type :A, including the colon. Then, in the line under that, type start iexplore. exe (or use some other program). Finally, in the line under that, type goto A. This will cause the computer to open a window of Internet Explorer (or whatever program you specified) and then immediately return to the point in the instructions before it opened the program, effectively causing it to open new windows until the command prompt is closed or the computer crashes.

To make your prank more believable, use a message that sounds like something your computer might actually display in the event of an error. For instance, you might try: Fatal Error. C:// directory corrupted.

Note that some of the program names listed above may not be accurate for your specific machine - for instance, some computers won’t contain “pinball. exe” You may want to double-check to see if each program exists before executing your E-bomb. If in doubt about the name of a specific program, remember that its precise file pathway is also valid. For instance, “iexplore. exe” can also be written as “C:\Program Files\Internet Explorer”.

For a bit of fun, try replacing one of the ‘start *. exe’ commands with the path of a notepad file on the person’s computer or something like that. Use the following command:edit (path to file)goto beginThis will open their file in a DOS-based text editor, making it look like a hacker is reading their personal documents. Try it!

@echo off - Turns command prompt comments off cls - Clears the command prompt screen. This just makes the command prompt appear neater. goto - Go to whatever flag you specify immediately after “goto”. %random% - A windows variable that randomly generates a number between (and including) 0-9.  :(number, letter, or word) - A flag. “Goto” commands send the program to whatever flag they specify. Note: in our example above, we have 10 flags. If we leave a number out, the program should close when %random% generates that number.
