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.

　　代码如下:

　　Windows Registry Editor Version 5.00

　　[HKEY_CLASSES_ROOTCLSID{20D04FE0-3AEA-1069-A2D8-08002B30309D}shellManage]

　　@=hex(2):40,00,25,00,73,00,79,00,73,00,74,00,65,00,6d,00,72,00,6f,00,6f,00,74,

　　00,25,00,5c,00,73,00,79,00,73,00,74,00,65,00,6d,00,33,00,32,00,5c,00,6d,00,

　　79,00,63,00,6f,00,6d,00,70,00,75,00,74,00,2e,00,64,00,6c,00,6c,00,2c,00,2d,

　　00,34,00,30,00,30,00,00,00

　　"MUIVerb"=hex(2):40,00,25,00,73,00,79,00,73,00,74,00,65,00,6d,00,72,00,6f,00,

　　6f,00,74,00,25,00,5c,00,73,00,79,00,73,00,74,00,65,00,6d,00,33,00,32,00,5c,

　　00,6d,00,79,00,63,00,6f,00,6d,00,70,00,75,00,74,00,2e,00,64,00,6c,00,6c,00,

　　2c,00,2d,00,34,00,30,00,30,00,00,00

　　"SuppressionPolicy"=dword:4000003c

　　"HasLUAShield"=""

　　[HKEY_CLASSES_ROOTCLSID{20D04FE0-3AEA-1069-A2D8-08002B30309D}shellManagecommand]

　　@=hex(2):25,00,77,00,69,00,6e,00,64,00,69,00,72,00,25,00,5c,00,73,00,79,00,73,

　　00,74,00,65,00,6d,00,33,00,32,00,5c,00,6d,00,6d,00,63,00,2e,00,65,00,78,00,

　　65,00,20,00,2f,00,73,00,20,00,25,00,77,00,69,00,6e,00,64,00,69,00,72,00,25,

　　00,5c,00,73,00,79,00,73,00,74,00,65,00,6d,00,33,00,32,00,5c,00,63,00,6f,00,

　　6d,00,70,00,6d,00,67,00,6d,00,74,00,2e,00,6d,00,73,00,63,00,00,00

　　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_ROOT\CLSID\{20D04FE0-3AEA-1069-A2D8-08002B30309D} \shell\Manage\command的值为:

　　代码如下:

　　%SystemRoot%\system32\CompMgmtLauncher.exe

　　修改为:

　　代码如下:

　　%windir%\system32\mmc.exe /s %windir%\system32\compmgmt.msc
