Prog en session admin va créer un dossier avec pleins droits pour tout le monde:

#define _WIN32_WINNT 0x0501
#include <windows.h>
#include "Sddl.h"

DWORD IsUserAdmin()
{
  BOOL b;
  SID_IDENTIFIER_AUTHORITY NtAuthority = SECURITY_NT_AUTHORITY;
  PSID AdministratorsGroup;
  b = AllocateAndInitializeSid(&NtAuthority,2,
    SECURITY_BUILTIN_DOMAIN_RID, DOMAIN_ALIAS_RID_ADMINS,
    0, 0, 0, 0, 0, 0, &AdministratorsGroup);
  if(b) {
    if(!CheckTokenMembership( NULL, AdministratorsGroup, &b)) b = FALSE;
    FreeSid(AdministratorsGroup);
  }
  return b;
}

BOOL CreateMyDACL(SECURITY_ATTRIBUTES * pSA)
{
  TCHAR szSD[] = TEXT("D:")
                 TEXT("(A;OICI;GA;;;WD)");
  if(NULL == pSA) return FALSE;
  return ConvertStringSecurityDescriptorToSecurityDescriptor(szSD, SDDL_REVISION_1, &(pSA->lpSecurityDescriptor), NULL);
}

int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE x, PSTR y, int z)
{

  PSECURITY_ATTRIBUTES psa = 0;
  if(!IsUserAdmin()) return 0;

    return 0;
