Windbg观察窗口的NTSTATUS将十进制改为十六进制显示

在Windbg里调试驱动时，NTSTATUS Status的值总显示为on-1**的十进制形式，非常不利于我们查看其对应的问题。如下：
这时，我们只需要使用dd命令显示变量的值即可。
2: kd> dd s
ffff8000`56fbf840 c0000010 fffff803 00000030 00000002
ffff8000`56fbf850 00000801 00000000 5dae2980 ffff9d8c
ffff8000`56fbf860 22461f75 ffffd32d 000001c8 00000000

ffff8000`56fbf8b0 098c1a20 ffff9d8c c6197020 fffff803
dd不光可以显示某个地址的内容，也可以显示某个变量或者寄存器指向的地址的值。
