无法打开组策略对象 - Windows 7 管理员

Question

每当我尝试访问本地组策略编辑器（或从管理工具文件夹访问本地安全策略）时，我都会收到以下消息：

“无法打开此计算机上的组策略对象。您可能没有适当的权限。

详细信息：未指明的错误”

请有人建议可能是什么问题？

我使用了注册表清理器，这可能造成了损坏。

细节

我以管理员身份使用 Windows 7 Professional。PC 是独立的 - 没有域控制器。

查看了管理事件日志，发现了很多这些：

Answer 1

我删除了 c:\windows\system32\GroupPolicy\Machine 下的机器 GPO .pol 文件

我必须先显示隐藏的文件和文件夹。

我重新启动并重新创建了一个新的本地策略。现在域 GPO 策略适用而不会失败。
