win7右键打不开计算机管理

我刚装的win7,可在桌面上右击计算机却打不开管理，

解决方法：
方法一：把regedit.exe改名为regedit.com，然后执行regedit.com，把HKEY_LOCAL_MACHINE\ Software\CLASSES\exefile\shell\open\command右边默认项的键值改为"%1" %*即可
方法二：（只适用于Win2000/XP）：
1、将cmd.exe改名为cmd.com或cmd.scr。
2、运行cmd.com
3、运行下面两个命令：
ftype exefile="%1" %*
assoc .exe=exefile
4、将cmd.com改回cmd.exe
方法三：当然是利用第三方工具了，如去下载瑞星的注册表修复器： http://download.rising.com.cn/zsgj/RegClean.com，利用它来修复一下文件关联。
方法四:
1、直接下载附件中的修复程序对系统关联进行一下修复；
2、点“开始”－“运行”,分别输入以下命令点“确定”
regsvr32 /i shdocvw.dll
regsvr32 /i shell.dll
regsvr32 /i shdoc401.dll
3、打开“我的电脑”，依次点“工具”→“文件夹选项”→“文件类型”，单击“新建”按钮打开“新建扩展名”对话框，在“文件扩展名”框中填入“exe”，接着单击“高级”，在“关联的文件类型”下拉框中选择“应用程序”，单击“确定”返回，最后单击“应用”后关闭对话框

把以下代码复制粘贴到文本文档（记事本）中保存退出，把记事本格式txt改为reg，双击它将信息导入注册表，确定即可。
