谁知道win7和window xp在屏蔽ctrl+alt+del有何不同？

[weixin_38087180]

xp下可以通过switch (ul_reason_for_call)    {    case DLL_PROCESS_ATTACH:        hSASWnd = FindWindow(TEXT("SAS Window class"), TEXT("SAS window"));        if (hSASWnd)             OldSASProc = (WNDPROC)SetWindowLong(hSASWnd, GWL_WNDPROC, (LONG)SASWindowProc);        break;    case DLL_THREAD_ATTACH:        break;    case DLL_THREAD_DETACH:        break;    case DLL_PROCESS_DETACH:        if (hSASWnd)             SetWindowLong(hSASWnd, GWL_WNDPROC, (LONG)OldSASProc);        break;获得SAS窗口。win7好像没有。有做过win7屏蔽热键的吗
