Configure the following settings to enable the a system crash using keyboard:

If you wish a crash dump file to be written, you must enable such dump files, choose the path and file name, and select the size of the dump file. For more information, see Enabling a Kernel-Mode Dump File.
With PS/2 keyboards, you must enable the keyboard-initiated crash in the registry. In the registry key HKEY_LOCAL_MACHINESystemCurrentControlSetServicesi8042prtParameters, create a value named CrashOnCtrlScroll, and set it equal to a REG_DWORD value of 0x01.
With USB keyboards, you must enable the keyboard-initiated crash in the registry. In the registry key HKEY_LOCAL_MACHINESystemCurrentControlSetServiceskbdhidParameters, create a value named CrashOnCtrlScroll, and set it equal to a REG_DWORD value of 0x01.
With Hyper-V keyboards, you must enable the keyboard-initiated crash in the registry. In the registry key HKEY_LOCAL_MACHINESystemCurrentControlSetServiceshyperkbdParameters, create a value named CrashOnCtrlScroll, and set it equal to a REG_DWORD value of 0x01.

You must restart the system for these settings to take effect.

After this is completed, the keyboard crash can be initiated by using the following hotkey sequence: Hold down the rightmost CTRL key, and press the SCROLL LOCK key twice.

The system then 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.

If a kernel debugger is attached to the crashed machine, the machine will break into the kernel debugger after the crash dump file has been written.

Defining Alternate Keyboard Shortcuts to Force a System Crash from the Keyboard

You can configure values under the following registry subkeys for different keyboard shortcut sequences to generate the memory dump file:

For PS/2 keyboards:
HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesi8042prtcrashdump
For USB keyboards:
HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServiceskbdhidcrashdump
For Hyper-V keyboards:
HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServiceshyperkbdcrashdump

You must create the following registry REG_DWORD values under these subkeys:

Dump1Keys
The Dump1Keys registry value is a bit map of the first hot key to use. For example, instead of using the rightmost CTRL key to initiate the hot key sequence, you can set the first hot key to be the leftmost SHIFT key.

Value	First key used in the keyboard shortcut sequence
0x01	Rightmost SHIFT key
0x02	Rightmost CTRL key
0x04	Rightmost ALT key
0x10	Leftmost SHIFT key
0x20	Leftmost CTRL key
0x40	Leftmost ALT key

Note You can assign Dump1Keys a value that enables one or more keys as the first key used in the keyboard shortcut sequence. For example, assign Dump1Keys a value of 0x11 to define both the rightmost and leftmost SHIFT keys as the first key in the keyboard shortcut sequence.

Dump2Key
The Dump2Key registry value is the index into the scancode table for the keyboard layout of the target computer. The following is the actual table in the driver.

Note Index 124 (sysreq) is a special case because an 84-key keyboard has a different scan code.

If you define alternate keyboard shortcuts to force a system crash from a USB or PS/2 keyboard, you must either set the CrashOnCtrlScroll registry value to 0 or remove it from the registry.

Limitations

It is possible for a system to freeze in such a way that the keyboard shortcut sequence will not work. However, this should be a very rare occurrence. Using the keyboard shortcut sequence to initiate a crash will work even in many instances where CTRL+ALT+DELETE does not work.

Forcing a system crash from the keyboard does not work if the computer stops responding at a high interrupt request level (IRQL). This limitation exists because the Kbdhid.sys driver, which allows the memory dump process to run, operates at a lower IRQL than the i8042prt.sys driver.
