使用NtUserBuildHwndList遍历窗口_win7x64

在我的上一篇文章中讲到
51604788

枚举窗口使用EnumWinodws是调用内核中NtUserBuildHwndList 这个函数最后2个参数必须是R3的地址

不然会返回0xC0000008错误,并且如果使用控制台窗口测试,这时ETHREAD下的win32Thread是NULL 也会返回0xC0000008错误

去实现的时候,返回成功了,但只传回线程的窗口HWND

然后去看了看win32k.sys的这个函数

下面是我修改了好的IDA F5这个函数

// typedef NTSTATUS (__fastcall *PFN_NTUSERBULIDHWNDLIST)(
//                                                 __int64 hDesktop,
//                                                 __int64 hWndParent,
//                                                 BOOLEAN bChildren,
//                                                 unsigned int dwThreadId,
//                                                 unsigned int lParam,
//                                                 OUT PVOID pWnd,
//                                                 OUT PVOID pBufSize);

}可以看到最后两个参数必须是R3的地址

否则返回0xC0000008错误,还有一点是如果这个线程的win32Thread是NULL的话也会返回0xC0000008错误(在控制台程序中出现)

修改后的代码,很明显可以知道如果dwThreadId是NULL的话就是枚举所有HWND

以下代码在win7 x64下测试通过

代码没有查询窗口的进程是谁

要查询的话只要调用

NtUserQueryWindow 即可得到

例如NtUserQueryWindow(hWnd,0);
