BootCompleteApp.exe
这个用来干啥的？
代码不过几行

1. 
   
2. int WINAPI WinMain(HINSTANCE hInstance,
   
3.                      HINSTANCE hPrevInstance,
   
4.                      LPTSTR     lpCmdLine,
   
5.                      int       nCmdShow)
   
6. {
   
7. 
   
8.     HANDLE BootCompleteEvent = OpenEvent(EVENT_ALL_ACCESS, FALSE, TEXT("OEM/BootCompleteEvent"));
   
9.     if (BootCompleteEvent == NULL)
   
10.     {
    
11.         RETAILMSG(1, (TEXT("[BootCompleteApp] ERROR: Notify OpenEvent() FAIL 0x%08X\r\n"), GetLastError()));
    
12.         CloseHandle(BootCompleteEvent);
    
13.         BootCompleteEvent = NULL;
    
14.     }
    
15.     else
    
16.     {
    
17.         RETAILMSG(1,(TEXT("[BootCompleteApp] Boot Complete Event Occured\r\n")));   
    
18.         ResetEvent(BootCompleteEvent);
    
19.         SetEvent(BootCompleteEvent);
    
20.     }
    
21.     return 0;
    
22. }
