Help I can't shut down my laptop

[dogememes]

Okay, so our teacher told us to download "safe exam browser", which is just a browser that you can't alt+tab or something like that. But now, I can't shut down my laptop, I can't open the task manager. I can't even log out! I have a HP EliteBook2570p windows 10.

You may have to find this file this guy used

And https/sourceforge.net/p/seb/bugs/69/

No wonder it makes it secure. It even locks the user out of it lol
