今天右键计算机-管理,居然提示"该文件没有与之关联的程序来执行该操作。请安装一个程序、或者，如果已安装程序，请在“默认程序”控制面板中创建关联."怀疑是自己上次用去除快捷方式造成的问题.下面是两种解决方法,我用了方法2就搞定了.

Windows Registry Editor Version 5.00

导入到注册表里就可以了,如果这个方法没有解决你的问题,请看方法2.

方法2:

打开注册表发现:

HKEY_CLASSES_ROOTCLSID{20D04FE0-3AEA-1069-A2D8-08002B30309D} shellManagecommand的值为:

%SystemRoot%system32CompMgmtLauncher.exe

修改为:

%windir%system32mmc.exe /s %windir%system32compmgmt.msc
