I have been trying to get windows 8.1 to force into a blue screen, but all of my attempts have failed. I don't really want to go into driver code or anything to do it, but just crash it using some sort of silly loop hole.
I tried creating the CrashOnCtrlScroll registry and it doesn't seem to work, even after restarting my computer. I also tried ending csrss, but microsoft has decided to let the user have no control and denies access at all costs (even after an informative prompt window).
I looked online for a while, but can't find anything on blue screening 8.1. It seems that everything out there is for 8 and below.
Notmyfault , a portable tool created by Microsoft's Mark Russinovich for the Windows Internals book will help you get a BSOD with more than a couple of ways (i.e High IRQ fault, hang IRP, stack trash, deadlock, etc)
