    • An operating system registry contains multiple “identities.” One of these identities is designated the current identity. An application executing on a multitasking computer system uses information stored in the current identity to configure the application, for example to provide a user-specific user interface. When an application opens, it registers with an identity manager using objects known as “connection points.” To switch identities, a user supplies the name of an identity to switch to. The identity manager then uses the registered connection points to query each of the applications for permission to switch identities. If all the registered connection points grant permission to switch identities, then the identity manager switches the current identity by changing information in the registry. The identity manager then notifies all applications, via their registered connection points, that a change to the registry has been made so that the applications can take appropriate action.
    • 操作系统注册表包含多个“身份”。 这些身份之一被指定为当前身份。 在多任务计算机系统上执行的应用程序使用当前身份中存储的信息来配置应用程序,例如提供用户特定的用户界面。 当应用程序打开时,它使用称为“连接点”的对象向身份管理器注册。 要切换身份,用户提供要切换到的身份的名称。 身份管理器然后使用注册的连接点来查询每个应用程序的权限以切换身份。 如果所有注册的连接点授予切换身份的权限,则身份管理器通过更改注册表中的信息来切换当前身份。 然后,身份管理器通过其注册的连接点通知所有应用程序已对注册表进行更改,以便应用程序可以采取适当的措施。
