Windows7/Vista下玩转老格式事件日志分析

Windows7之家（www.908098.com）：Windows7/Vista下玩转老格式事件日志分析
【注意，本文不适合初级电脑用户】
如果有一个，一个朋友对你说他的电脑出现了问题，可能，你需要去分析它的系统的事件日志。毕竟，在Windows系统里面，系统事件日志里面记录了太多的信息，应用程序的使用、崩溃等记录，Windows系统的各种事件记录等等。然而，当你的朋友把他的Windows目录下的日志发过来，你想进行查看分析的时候，却发现，提示事件日志崩溃！
这是怎么回事呢？
原因很简单，Vista之前事件日志是.evt文件，Vista及之后是.evtx文件！
我们可以用微软提供的Log Parser 2.2（点击进入微软官方页面），它能在相应的系统上解析各自支持的格式，解析命令为：

logparser -i:EVT "SELECT * INTO a.csv FROM b.evt"

但如果在Vista、Windows Server 2008、Windows7及之后系统上解析.evt格式日志可能会提示事件日志崩溃，这时需要将.evt格式转换为.evtx格式，幸运的是Vista及之后的系统提供了Wevtutil－Windows Events Command Line Utility这个工具！
运行命令：wevtutil epl application.evt application.evtx /lf:true 就能转化。

wevtutil 在系统里面的提示都是英文，：
