Windows 7 IE 8 不能显示png图片了
Windows 7 en-us IE 8不能显示png图片。
已尝试的方法：
1. 提得最多的方法：regsvr32 pngfilt.dll
收到错误消息The module “pngfilt.dll” was loaded but the entry-point DllRegisterServer was not found. Make sure that “pngfilt.dll” is a valid DLL or OCX file and then try again.
附：注册shdocvw.dll, mshtml.dll, browseui.dll这几个dll时也出现了同样的错误消息。
2.国外论坛上说让扫描pngfilt.dll文件是否已损坏
我就以Administrator身份运行了sfc/scannow，结果是没有任何错误。
3.卡饭论坛的方法
打开注册表，依次展开HKEY_CLASSES_ROOT\MIME\Database\Content Type\image/png，找到Extension键名，将数值数据改为.png，找到Image Filter CLSID键名，数值数据改为{A3CCEDF7-2DE2-11D0-86F4-00A0C913F750}。
可是我看了一下我的注册表，这几个键值本来就是这样的。
4.在Control Panel -> Turn Windows Features on or off里关闭IE，然后重新打开此功能。这相当于把IE卸载再重装，但仍不能解决问题。
What can I do to save Internet Explorer 8 ?
[解决办法]
可以装一个插件试试看， 我以前的也不可以看， 后面的时候装一个插件就可以用了。
[解决办法]
我也遇到过这个问题，不过解决了，按照我的办法应该可以解决。（好像是打过补丁后出现的）
将下面段代码考下，然后保存为XXX.reg格式文件，然后运行。最后重启IE就OK了。

[解决办法]
我发现IIS功能也打不开了，所以就干脆重装了Windows
