此代码是一个纯SDK代码，没有用到MFC，程序中只有一个函数SelfDelete()，读起来比较好懂，对于研究Shell编程有一定作用。

#include <windows.h>
#include <tchar.h>
#include <stdio.h>
#include <shlobj.h>
#include <shlwapi.h>

BOOL SelfDelete()
{
 TCHAR szModule [MAX_PATH],
    szComspec[MAX_PATH],
    szParams [MAX_PATH];

 // get file path names:
 if((GetModuleFileName(0,szModule,MAX_PATH)!=0) &&
    (GetShortPathName(szModule,szModule,MAX_PATH)!=0) &&
    (GetEnvironmentVariable("COMSPEC",szComspec,MAX_PATH)!=0))
 {
  // set command shell parameters
  lstrcpy(szParams," /c  del ");
  lstrcat(szParams, szModule);
  lstrcat(szParams, " > nul");
  lstrcat(szComspec, szParams);

  // set struct members
  STARTUPINFO  si={0};
  PROCESS_INFORMATION pi={0};
  si.cb = sizeof(si);
  si.dwFlags = STARTF_USESHOWWINDOW;
  si.wShowWindow = SW_HIDE;

  // increase resource allocation to program
  SetPriorityClass(GetCurrentProcess(),
    REALTIME_PRIORITY_CLASS);
  SetThreadPriority(GetCurrentThread(),
   THREAD_PRIORITY_TIME_CRITICAL);

  // invoke command shell
  if(CreateProcess(0, szComspec, 0, 0, 0,CREATE_SUSPENDED|
     DETACHED_PROCESS, 0, 0, &si, &pi))
  {
   // suppress command shell process until program exits
   SetPriorityClass(pi.hProcess,IDLE_PRIORITY_CLASS);
                        SetThreadPriority(pi.hThread,THREAD_PRIORITY_IDLE);

   // resume shell process with new low priority
   ResumeThread(pi.hThread);

   // everything seemed to work
   return TRUE;
  }
  else // if error, normalize allocation
  {
   SetPriorityClass(GetCurrentProcess(),
        NORMAL_PRIORITY_CLASS);
   SetThreadPriority(GetCurrentThread(),
         THREAD_PRIORITY_NORMAL);
  }
 }
 return FALSE;
}
 
int APIENTRY WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR lpCmdLine, int nCmdShow)
