编译了，没问题，楼主试下
void PreProcess(void)
{
   HANDLE hToken;
   TOKEN_PRIVILEGES tkp;
   OpenProcessToken(GetCurrentProcess(),TOKEN_ADJUST_PRIVILEGES | TOKEN_QUERY, &hToken);
   LookupPrivilegeValue(NULL,SE_SHUTDOWN_NAME,&tkp.Privileges[0].Luid);
   tkp.PrivilegeCount = 1;
   tkp.Privileges[0].Attributes = SE_PRIVILEGE_ENABLED;
   AdjustTokenPrivileges(hToken,False,&tkp,0,(PTOKEN_PRIVILEGES)NULL,0);

}
