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:<p>Windows Registry Editor Version 5.00</p><p>[HKEY_CLASSES_ROOTCLSID{20D04FE0-3AEA-1069-A2D8-08002B30309D}shellManage]</p><p>@=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,</p><p>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,</p><p>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,</p><p>00,34,00,30,00,30,00,00,00</p><p>"MUIVerb"=hex(2):40,00,25,00,73,00,79,00,73,00,74,00,65,00,6d,00,72,00,6f,00,</p><p>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,</p><p>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,</p><p>2c,00,2d,00,34,00,30,00,30,00,00,00</p><p>"SuppressionPolicy"=dWord:4000003c</p><p>"HasLUAShIEld"=""</p><p>[HKEY_CLASSES_ROOTCLSID{20D04FE0-3AEA-1069-A2D8-08002B30309D}shellManagecommand]</p><p>@=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,</p><p>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,</p><p>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,</p><p>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,</p><p>6d,00,70,00,6d,00,67,00,6d,00,74,00,2e,00,6d,00,73,00,63,00,00,00</p>

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
