    How to Enable or Disable BSOD Crash on Ctrl+Scroll Lock in Windows

    information   Information
    A blue screen 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.

    I have no Scroll Lock key on my keyboard (like most of us with a laptop I guess)

    So I am trying to use the crashdump registry key with the 2 subkeys Dump1Keys and Dump2Key to define a custom keyboard shortcut for this feature.

    But this does not work.
    I defined Dump1Keys to 0x11 (left and right shift) and Dump2Key to 0x52 (Insert key).

    Am I wrong with key code ? The MS doc is not really crystall clear on this.

    So I re-read the instructions carefully and I find out my error.

    You need to use the index of the table provided as Dump2Key value. Sight!! So now I use 0x64 (100) for Insert.

    And check also the type of your keyboard in Device Manager (there is PS/2 keyboard on laptops). Mine was PS/2 and I needed to use i802prt key.

    ... But, this is still not working for me.

    Hello THNU85DC3sd, :)

    I'm not sure this will work with any other key combination.

    Did you restart the computer afterwards to apply?

    Yes, I rebooted every time.

    So I get it working.
    First the index of the table starts at 0, so I must have used 0x63. But 2 shift keys + insert did not work. I don't know why.

    So I used ctrl+Alt+U (Dump1Keys=0x60 and Dump2Key=0x17) and it worked that way.

    Hint: You have to press twice the key. Like ctrl-alt then u-u rapidly.
