IE8.0，相比IE7新增了很多功能。但是由于兼容性问题以及使用习惯等原因，一些人需要改回的IE7.0但是在卸载的时候发现，在“控制面板”的“添加/删除程序”中并没有直接提供卸载选项，不仅Xp有主要的问题，在Vista中同样存在这个问题。该如何解决这个问题呢，下面提供几个方法供大家选择：

1.从“更新程序”中卸载。如果你的系统是XP SP2或SP3的话，打开“控制面板”中的“添加/删除程序”，然后选中面板上方的“显示更新程序”，在这里面找到Internet Explorer 8的更新项，删除；
2.可以试试“添加/删除程序”左侧的“添加/删除Windows组件”，然后把Internet Explore前面的勾去掉，下一步不过这样会彻底删除Internet Explorer，导致依赖程序无法运行，而第一种方法会使Internet Explorer在重新启动计算机后回到前一个版本；
3.使用Windows优化大师、360安全卫士一类自带的“智能卸载工具”完整卸载IE，不过卸载后你需要重新安装一个IE7.0
4. 最后推荐一个最有效的办法，那就是直接运行C:＼WINDOWS＼ie8＼spuninst＼spuninst.exe

取消win7文件自动排列功能（对任意文件夹有效)
WIN7的操作的确比XP华丽不少，但并不是适合每个人的口味。比如它对文件夹的自动排列就有点自作多情，而且还不提供取消办法，没办法，只能在在网上搜个方法——改注册表。

步骤/方法
1.运行附件中的注册表文件
2.任意打开一个文件夹
3.把图标变成中号图标
4.空白位置，点击右键→查看→取消“对齐网格”(这个可以无视) 和“自动排列”
5.在文件夹的工具栏，选择工具→选项→查看→应用到文件夹
6.关闭文件夹，再次打开文件夹
7.你会发现可以随意拖动文件/文件夹，而不会系统自动排列了，问题得到解决
（如果无效，请重启电脑）

注意事项
注意,使用前请先备份注册表！
