How To Enable or Disable BSOD Crash on Ctrl+Scroll Lock in Hyper-V In Windows 11?

Windows 11

As a windows user, you must have encountered the blue screen error at least once. A BSOD(Blue Screen Of Death) error is a kernel-level failure due to issues with the Windows driver or hardware. Blue screen deaths are not like application crashes; for a typical application crash, windows continue to function; however, for the BSOD error, windows is completely paralysed. If the BSOD occurs on your system, you won’t be able to access any of the features, such as the Start menu or the taskbar; instead, windows will present you with a blue screen stating the error message.

For many various reasons, we need to manually trigger a BSOD crash. The cherry on the cake, Windows has this hidden feature using which you can manually trigger a BSOD crash by holding down the right Ctrl + Scroll Lock key twice in the guest virtual machine( Hyper-V gen 1 or gen 2). In this article, we’ll walk you through the steps to enable or disable this feature on your Windows 10 or 11 machine.
