昨天在WSUS服务器上批准了IE7.0的补丁，后面发现好多客户端用不了。
出现如下所示的错误提示：
The requested lookup key was not found in any active activation context.（不知道这里
怎么发图片上来，…^---^)
我在微软上面找到两种解决方案：如下
一种是在控制面板当中直接删除
一种是
1. Click Start, click Run, type %windir%\ie7\spuninst\spuninst.exe, and then click OK.Note In this command, %windir% points to the DriveWindows folder. The placeholder Drive represents the hard disk partition that contains the Windows operating system files. By default, the IE7 folder is a hidden folder. Therefore, you may have to make this folder visible. To do this, follow these steps:
1. Open Windows Explorer.
2. On the Tools menu, click Folder Options.
3. Click the View tab.
4. In the Advanced settings list, under Hidden files and folders, click Show hidden files and folders, and then click OK.
2. Follow the wizard instructions to uninstall Internet Explorer 7.
3. After you uninstall Internet Explorer 7, double-click the Internet Explorer icon to verify that Internet Explorer 6 is restored.


问题是现在有些机器删除不了，删除了重启显示的ＩＥ是6.0的界面，但是在help
about internet explorer看到的还是7.0的，内核没有删掉。
有没有那位兄弟碰过这种问题的，望能够帮忙想出解决方法。谢谢！！

没有人碰过这种情况吗？望高手前来共同讨论，我今天检测过防火墙，杀毒软件没有任何问题。在安全模式下也不行，在国外的网站上关于这个的介绍也不多，而且试了都没有用。
