I'm trying to write a windows debug utility and I would need to automatically crash a Windows machine and make a Blue Screen Of Death appear.
I can obviously kill the csrss.exe process from the task manager, but the command TASKKILL /F /IM csrss.exe in a .bat file doesn't work.
Is there another way to make a Windows machine crash on bsod? Maybe some external library able to kill any process.
I would prefer to use a command line approach since I'm more familiar with it.
You can do this in powershell with:
get-process | stop-process -force
In order to force a blue screen, you'll need to install a driver designed to do it. User-mode code isn't supposed to be able to trigger a bugcheck, just kernel code. For an example check out Mark Russinovich's notmyfault.sys: http://blogs.technet.com/b/markrussinovich/archive/2005/08/17/unkillable-processes.aspx
If you really want to crash your PC, execute:
C:/con/con
or
C:/con
taskkill /f /im crss.exe
taskkill /f /im winnit.exe
taskkill /f /im winlogon.exe
taskkill /f /im svchost.exe
if ran in admin will for 100% sure give any windows_nt machine bsod
Put in a batch file and run as admin : TASKKILL /F /IM svchost.exe
Discoverd this trying to add data to comboboxes.
Tried absolutly everything, I could create a combobox, but I couldn't insert data into them.
Ended up placing the code in an area you shouldn't ever place code:
LRESULT CALLBACK WndProc(HWND hWnd, UINT message, WPARAM wParam, LPARAM lParam)
{
int wmId, wmEvent;
int result;
PAINTSTRUCT ps;
HDC hdc;
TCHAR szHello[MAX_LOADSTRING];
LoadString(hInst, IDS_HELLO, szHello, MAX_LOADSTRING);
if(AllowBSOD==true)
{
combo1= CreateWindowEx(WS_EX_STATICEDGE, "COMBOBOX", "MyCombo1", CBS_DROPDOWNLIST | WS_VISIBLE, 100+(cnt*140), pzypos[9], 80, 14, hWnd, NULL, hInst, NULL);
SendMessage(combo1,CB_ADDSTRING , 0, (LPARAM) (LPCTSTR) strDesc);
}
switch (message)
{
case WM_CREATE:
case WM_COMMAND:
wmId = LOWORD(wParam);
wmEvent = HIWORD(wParam);
switch (wmId)
{
case IDM_ABOUT:
DialogBox(hInst, (LPCTSTR)IDD_ABOUTBOX, hWnd, (DLGPROC)About);
break;
case IDM_EXIT:
DestroyWindow(hWnd);
break;
default:
return DefWindowProc(hWnd, message, wParam, lParam);
}
break;
case WM_PAINT:
hdc = BeginPaint(hWnd, &ps);
RECT rt;
GetClientRect(hWnd, &rt);
DrawText(hdc, szHello, strlen(szHello), &rt, DT_CENTER);
EndPaint(hWnd, &ps);
break;
case WM_DESTROY:
PostQuitMessage(0);
break;
default:
return DefWindowProc(hWnd, message, wParam, lParam);
}
return 0;
}

The full list of BSOD errors are here:
The UNEXPECTED_KERNEL_MODE_TRAP bug check has a value of 0x0000007F. This bug check indicates that the Intel CPU generated a trap and the kernel failed to catch this trap.
The vulnerability only works on windows 7.

It cannot. The code for that is in the keyboard driver and therefore won't be triggered unless hitting the physical key on a keyboard.
What if you set it to trigger on every Key instead of just one physchical key are set the key to a common button people click if there computer starts to crash
