win7计算机管理打不开 该怎么办？？？

将下列文字用复制到记事本里，然后将其后缀名改为.reg，（如果没出现后缀名，点击“计算机-组织-文件和搜索选项-查看-隐藏已知文件的文件名”将其前面的钩去掉就好了）也就是注册表文件，然后双击此文件，将其导入注册表。

开始－－运行－－gpedit.msc
打开组策略
定位到
用户配置－管理模板－windows组件－windows资源管理器－隐藏windows资源管理器上下文菜单上的“管理”项目
设置为
未配置

可以试一下从运行里输入：compmgmt.msc 就可以打开。
不行的话打开注册表，找到以下值：
[HKEY_LOCAL_MACHINE\SOFTWARE\Classes\CLSID\{20D04FE0-3AEA-1069-A2D8-08002B30309D}\shell\Manage\command]

将“默认”的值改为“mmc.exe %windir%\system32\compmgmt.msc”

我误装了KB977165后也出现了这个对话框，卸载了那个补丁后还是不可以。因为我用的是盗版系统，而那个补丁据说好像安装后要求提升什么使用权限，好像是为了保护正版。最后，我一键还原了，用正版的vista。至于上面提示的操作，没试过。重新装系统···

“重新注册一下msxml
parser，命令如下,开始菜单-运行,输入：
regsvr32
C:\Windows\system32\msxml3.dll
再回车,所有问题解决
