WARNING! The following is a trick that you should only do to someone you know very well, that will not file charges against you for destruction of property. You should also be prepared to completely reinstall windows and additional software, and perhaps make a complete backup of their drive so you can make it the way it was after your malicious prank has taken its toll.


THE PRANK
anyone ever write a batch file that destroys the autoexec upon startup? thats a fun quick trick to do on an unsuspecting friend. The best thing, is that you don't see the results until the computer is turned off, and turned back on. Upon the startup after you install the code, it will be completely whack and require the windows disk and/or complete format


Use the following dos commands to

copycon afile.bat
cd\
del autoexec.bat
press CTRL+Z to end COPYCON

go to your C:

type edit autoexec.bat
place the file path in with the other file paths, but place it first.


save and walla

next time computer starts,,, lol it wont.


Batch files are FUN!


Or you could just delete the code in the autoexec file when you have it open for edit.. but what is the fun in that.

Consider this as well, instead of deleting the exec file, why not make the computer say something funny upon startup? Create an option command that says something deragotory like "If you like to abusar el polio en la casa, press y" If they press N, make the system terminate the startup by adding some loop code. If they press Y, make the computer load like normal. Abusar el polio en la casa means "molest chickens in the house"

Actually, all it will require is a restore of one file, autoexec.bat, and on a modern computer, even that really isn't necessary.

Sure it will! I just won't run whatever custom DOS startup code had been in place. That won't prevent the computer from operating, and it won't prevent Windows from loading and running normally. It won't even prevent the Windows startup programs from running, which is how people do this type of configuration nowadays.

The last time i did this was a LONG time ago, windows ME xp sp1 era I wouldn't be surprised if it doesn't work anymore...

You could have it delete all non-locked files in C:\WINDOWS and C:\WINNT... =P

A better idea would be to rename autoexec.bat to autoexec.tmp, It won't run, but by just renaming it to autoexec.bat everything is fixed!
