如何解决win7开机关机很慢的问题(一)

2011-08-06

老婆的同事，两年前买的笔记本，开机时间2分钟以上。说让我给看看。但windows有一点不好，看不到开机详情，所以也不知道什么东西在加载过程中耗费了时间。所以我就按照通常的方式，做了如下的步骤： 1.将启动里面的程序删除。 2.运行regedit，搜索run，只选“项”，全字匹配。到注册表中将可疑的无用的启动删除。 3.如果可以，还可以看看服务里有没有没必要的服务，可以禁止启动。 4.并且卸载一些看起来无用的自启动程序。

但这样操作完后，开机时间1分30秒，并无多大改观。一些第三方的软件，如360，QQ电脑管家，会提示一些优化项目，但还是不能从根本上解决问题。启动依然很慢。

补充：网友Alex 在本文的评论附了微软提供的autoruns程序，可以很方便管理启动项，服务，右键菜单，IE加载项等。不过没有看到中文版。

能否查看启动的命令行详情呢？开机时用F8进入，有命令行模式。但只显示了一部分命令行，又转入图形界面了，吐血！那能否用日志记录的方式呢？同样开机用F8进入，选日志记录模式，提示将日志记在windows的ntbtlog.txt,可是该文件打开看到的是：

Microsoft (R) Windows (R) Version 6.1 (Build 7600)
8 6 2011 07:44:12.610
Loaded driver SystemRootsystem32ntoskrnl.exe
Loaded driver SystemRootsystem32hal.dll
Loaded driver SystemRootsystem32kdcom.dll
Loaded driver SystemRootsystem32mcupdate_GenuineIntel.dll
Loaded driver SystemRootsystem32PSHED.dll
Loaded driver SystemRootsystem32CLFS.SYS
...

记录启动日志居然连时间都没有？？？？何必为我省这点空间？？？？快哭了！

微软提供了日志管理器，其中的Microsoft-Windows-Diagnostics-Performance/Operational 有启动性能监视。

点开后，可以设置100-110启动性能事件过滤。如我的100事件，详情。可以通过友好视图和xml视图来显示。

各事件耗费的时间（毫秒ms)，都有记录。如我计算机中的数据：

各个项目的意思，在OnOffTrans.docx中有解释。OnOffTransPerf由微软提供, 讲如何将启动时间提高到10秒。官方下载地址：http://msdn.microsoft.com/en-us/performance/cc825801

因为系统启动时，分两个阶段。第一阶段是到加载关键路径代码以启动桌面进程，第二阶段是到系统进入idle，期间系统加载很多后台服务。

微软其实有诊断程序。在win7的sdk里自带。
