删除
C:\WINDOWS\system32\winsearch.dll
C:\WINDOWS\system32\Gdcmo.dll
C:\WINDOWS\DOWNLO~1\nuqeldky.dll
C:\WINDOWS\system32\qylhelper.dll
C:\!wb\wnwb.exe
C:\!wb\wnwb_up.exe

后两项是万能五笔输入法，要删除吗？
C:\WINDOWS\DOWNLO~1\nuqeldky.dll 这一项没有找到
C:\WINDOWS\system32\winsearch.dll 这一项不让删

我的是一个小时重起一次  "关机是由NT AUTHORITY\SYSTEM初始的"

先结束C:\WINDOWS\system32\winsearch.dll  再删除  或安全下删除

我发现问题的原因了，但找不到解决的办法
我前一次曾用优化大师更改了鼠标的右键设置，错误地把右键里打开删除，换成了关闭计算机，所以后来每次双击我的电脑或者双击文件夹，系统都会自动提示关机。昨天我又用优化大师取消了右键里的关闭计算机后，再双击系统就不会关机了。
但又有了一个问题，这回出现的是搜索页面，我一看，右键的第一项变成“搜索”了，哪位高手可以告诉我，怎么样可以把右键里的第一项改回“打开”，我想只要改回去就会好了
谢谢。最好能讲得详细一点，我是个菜鸟

弄好了，谢谢大家，我用瑞星的注册表修复工具，把文件关联一项修复了，就好了
