这个服务还在.
[Distributed File System Services / Distfsv]
<C:\WINDOWS\System32\Distfsv.exe -service><N/A>
请删除.
另,修复一下.TXT文件关联.

重新启动到安全模式（进入安全模式的方法:重新启动电脑, 开机自动检测完后, 按[F8]键(可以一直按到启动菜单出来为止), 选择安全模式(Safe Mode)进入Windows。）

开始→控制面板→性能和维护→管理工具→服务→查找Distributed File System Services→右击→属性→启动类型→禁止→应用→停止→确定。

然后打开我的电脑→再点工具→打开文件夹选项→查看→把隐藏受保护的系统文件（推荐）和隐藏已知文件类型的扩展名的勾去掉→再显示所有文件→找到以下文件并删除：(如果有的话)
C:\WINDOWS\System32\Distfsv.exe 
C:\WINDOWS\System32\Distfsv1.dll
C:\WINDOWS\System32\Distfsv2.dll

最后请修复TXT 文件的关联
