这一项你说明一下。
C:\Program Files\Common Files\Microsoft Shared\MSINFO\windll32.exe
你删除了它没有，有什么反应
建议你把windll32.exe发到twtxk@126.com

找不到C:\Program Files\Common Files\Microsoft Shared\MSINFO\windll32.exe
有类似的Explorer.exe "C:\Program Files\Common Files\Microsoft Shared\MSINFO\windll32.exe"
C:\Program Files\Common Files\Microsoft Shared\MSINFO里也找不到windll32.exe

我删除
Explorer.exe "C:\Program Files\Common Files\Microsoft Shared\MSINFO\windll32.exe"
提示说这个项对系统很重要，不能删，但是可以双击或点编辑按钮编辑它

呵呵，是我没说对。
你这样。
点编辑，删除"C:\Program Files\Common Files\Microsoft Shared\MSINFO\windll32.exe"
就好。
还有异常你描述一下。

编辑是不是把Explorer.exe "C:\Program Files\Common Files\Microsoft Shared\MSINFO\windll32.exe"改成"C:\Program Files\Common Files\Microsoft Shared\MSINFO\windll32.exe"
（要加引号吗？）然后删除吗？

不是，是删除C:\Program Files\Common Files\Microsoft Shared\MSINFO\windll32.exe

在编辑那直接删除C:\Program Files\Common Files\Microsoft Shared\MSINFO\windll32.exe
然后再硬盘的C:\Program Files\Common Files\Microsoft Shared\MSINFO\删除windll32.exe
