This tutorial will show you how to enable or disable the ability to manually force a BSOD crash on Ctrl+Scroll Lock for all users in Windows 10 and Windows 11.

A BSOD (blue screen of death) error (also called a stop error) can occur if a problem causes your PC to shut down or restart unexpectedly (aka: crash). When you experience this type of error, you won’t be able to see things like the Start menu or the taskbar on the screen when your PC is turned on. Instead you might see a blue screen with a message that your PC ran into a problem and needs to restart.

Windows has a hidden feature that you can enable to be able to manually force a BSOD by holding down the rightmost Ctrl key, and press the Scroll Lock key twice.

When used, the system calls KeBugCheck and issues bug check 0xE2 (MANUALLY_INITIATED_CRASH). Unless crash dumps have been disabled, a crash dump file is written at this point.

You must be signed in as an administrator to enable or disable the BSOD crash on Ctrl+Scroll Lock feature.
