0

Do you know if you can manually trigger a BSOD, the Windows famous Blue Screen of Death, on any Windows computer from a PS2 or USB keyboard? Yes, the hidden feature, called Crash on Ctrl-Scroll, can trigger an intended crash to collect a memory dump for developing or debugging purpose when enabled.

If you are interested, here is how you can enable it.

For USB keyboard

Open Registry Editor, and navigate to the following location:

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\kbdhid\Parameters

And created a new DWORD-32 value called CrashOnCtrlScroll and set its value to 1.

Restart the computer for the setting to take effect.

For PS2 keyboard

Open Registry Editor and navigate to the following location:

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\i8042prt\Parameters

And created a new DWORD-32 value called CrashOnCtrlScroll and set its value to 1.

Again, restart the computer for the setting to take effect.

To initiate the manual crash, press and hold Ctrl key and press Scroll Lock key twice.

Bonus tip: if you don’t want the computer auto-restart after the crash for debugging purpose, you can disable it from Advanced tab in System Properties.

Run SystemPropertiesAdvanced from Run dialog box, go to Settings under Startup and Recovery section, and uncheck the “Automatically restart” option off.
