So, a lot of people really like to do computer pranks, especially at school, though most require CMD (Command Prompt), which is blocked. I will show you how, using notepad, the easiest way possible (Anyone can do this, you don't need to be a wiz).
Step 1: Open New Notepad File
First, You'll have to open up the program Notepad. (All Programs>Accessories>Notepad)
Step 2: To the Typing!
All you have to type in the window is:
Make sure there is a space after the word "command"!
Step 3: Saving
If you are not a computer wiz, this will be interesting!
When you save, click "Save As..."
Then name your file "CMD.bat"
(the ".bat" is important!)
Instead of saving it as a ".txt" file, choose "All Files".
Save to Desktop or where ever you want.
Click the icon and enjoy CMD!
