Regarding your RunDLL32 issue-- This is the result of the IE7b2p uninstall failing to clear the old runddl32.exe background sync task.Go into Control Panel | Performance and Maintenance | Scheduled Tasks.
Find the task that is calling rundll32 and delete that task.It should be fine after that.
有关你提出的RunDLL32的问题--这是因为在你卸载IE7b2p时未能将原来的(老的)后台同步程序rundll32.exe清理干净.请进入控制面板/性能与维护/计划任务.
找到叫做rundll32的任务并删除它,之后问题应该就解决了.
IE7好象现在并不好用,有些东西与现在的WINDOWS XP兼容性并不好,应该是与VISTA一起发布的.
