    How do I make a batch file that activates on startup?
    Community Answer
    Community Answer
    Open Notepad and type in: @echo off start "" "cmdprank.bat." Save it as any name, but make sure it has .bat or .cmd at the end of the filename. Then, follow Method 1, not Method 2.
  • Question
    All I have to do is turn the computer back on afterwards?
    Community Answer
    Community Answer
    Turning the computer back on after one of these programs crashes will not result in any problems. These programs will not do anything if you don't open them. However, putting one of them in the startup folder is not a very good idea, because they will start as soon as the computer starts, then crash it immediately.
  • Question
    Can I kill programs other than file explorer? Like Google Chrome?

    Yes, you can. Use "chrome.exe" for Google Chrome. You need to have the name of the process to kill a task.
  • Question
    Is kill -f explorer.exe for canceling shutdown?
    Community Answer
    Community Answer
    It is how you can navigate in Windows. If killed, it will leave the desktop inacessible and only have the background in it. A critical task is wininit.exe, which will initiate BSoD.
  • Question
    Can this harm my PC?
    Community Answer
    Community Answer
    No, it can't. It is safe. With the cmd spam way, just make sure to unplug the computer quickly.
  • Question
    Why do I get sent back to the notepad when I open the file?
    Community Answer
    Community Answer
    Your default program is Notepad, so right click and choose Open With. You should be able to change the default program. If not, then it's not a bat file.
  • Question
    How do you reopen the computer when it crashes?

    If it shows a blue screen with white letters, wait for it to restart, or if the whole PC crashes, restart the PC.
