电脑蓝屏无法进入系统，如何获取原系统IP配置？

不少公司或者企事业单位的电脑是固定IP地址，一旦电脑出现蓝屏死机，无法进入系统，那么要想知道这台电脑的IP配置，是个麻烦事儿。重装系统后随便固定个IP地址吧，又怕IP冲突。那么有没有办法在无法进入系统的情况下获取原系统的IP配置呢？答案是肯定的。今天就来讲一个PE里获取目标系统IP配置并保存到U盘的方法。这个方法的前提是电脑硬件没坏（感觉是废话）！接下来就说下思路：通过查看注册表来找原来系统的IP地址信息。

通过cmd命令的reg命令读取注册表实现查看原来系统的IP地址信息

将以下代码保存为获取网卡名称及IP信息.cmd

@echo off 2>nul 3>nul
setlocal enabledelayedexpansion
