Istnieje program usuwania własnego

<code>#include <windows.h>
#include <stdio.h>

void main(int argc, char* argv[])
{
    STARTUPINFO si = {0};
    PROCESS_INFORMATION pi = {0};
    si.cb = sizeof(si);

    if (argc == 1)
    {
        SECURITY_ATTRIBUTES sa;
        sa.nLength = sizeof(sa);
        sa.lpSecurityDescriptor = NULL;
        sa.bInheritHandle = TRUE;

        CopyFile(argv[0], "1.exe", FALSE);
        MoveFile(argv[0], "2.exe");

        CreateFile("1.exe", 0, FILE_SHARE_READ, &sa, 
            OPEN_EXISTING, FILE_FLAG_DELETE_ON_CLOSE, NULL);

        CreateProcess(NULL, "1.exe x", NULL, NULL, 
            TRUE, 0, NULL, NULL, &si, &pi);
    }
    else if (argc == 2)
    {
        while(!DeleteFile("2.exe"));

        CreateProcess(NULL, "net", NULL, NULL, TRUE, 
            DEBUG_ONLY_THIS_PROCESS, NULL, NULL, &si, &pi);
    }
}
</code>

Jeśli to usunę:CreateProcess(NULL, "net", NULL, NULL, TRUE, DEBUG_ONLY_THIS_PROCESS, NULL, NULL, &si, &pi); to nie działa.
Czy ktoś mógłby mi wyjaśnić, jak to działa?
