win7升级ie8至ie11后无法打开，表现为
1、双击无反应，进程中没有ie进程。
2、卸载ie11后，连ie8也无法使用路。
3、检查windows功能，ie是启用的。
4、想起来用CCleaner进行过清理。
5、连打开文件夹变成了打开新窗口，而设置里是在同一窗口打开。
解决办法：
运行
regsvr32 "%SystemRoot%System32actxprxy.dll"
regsvr32 "%ProgramFiles（x86)%Internet Explorerieproxy.dll"解决路文件夹新窗口打开问题，IE可以打开几秒，随后自动退出。

最后用360急救箱扫描，发现有2项IE动态库被劫持。
选择修复，IE恢复正常。
