手动删除Windows XP SP2多余文件

安装完Windows XP SP2和一系列补丁后，你会发现系统分区少了几百兆空间。经检查发现，在C:\Windows目录下有着不少以$NtUninstal开头的文件，有的可能还有$NtServicePackUninstall$和ServicePackFiles文件夹。下面介绍一下这些文件夹的来源。

       1.$NtServicePackUninstall$文件夹

          它是当卸载SP2时所需要的文件夹，当其被删除后就不能通过控制面板来删除SP2了。其实目前大多数系统安装盘都集成了Windows XP SP2，当系统安装完成后就不存在$NtServicePackUninstall$文件夹了。只有在SP1的情况下安装SP2升级包才会出现这个文件夹。如果不打算卸载SP2的话，这个文件夹完全可以删除。

       2.ServicePackFiles文件夹
     
          此文件夹中存在的是SP2安装文件，如果删除了，当添加新功能时可能要插入SP2的安装光盘。如果你的系统安装盘已经集成了SP2，那么也可以删除此文件夹。

       3.以$NtUninstal开头的文件夹

          安装补丁文件后产生的文件，用来卸载补丁文件。一般补丁安装了是不会卸载的，因此可以删除以释放空间
