WebBrowser控件默认使用的IE（只能是IE，Google的chrome和Firefox都不行）的内核基本是比较低的版本，所以到导致WebBrowser无法载入主流的网页。根据下面的操作就可以实现修改默认IE内核。
1.确定运行程序的Window的属于32bit还是64bit的。注册表设置的位置不同。
32bit：
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorer\MAIN\FeatureControl\FEATURE_BROWSER_EMULATION]
"Spider.exe"=dword:0000270f
"Spidesssr.vshost.exe"=dword:0000270f
64bit：
[HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Internet Explorer\MAIN\FeatureControl\FEATURE_BROWSER_EMULATION]
"Spider.exe"=dword:0000270f
"Spider.vshost.exe"=dword:0000270f
以上的可以保存到文本文件修改后缀为“.reg”直接运行即可，或者可以根据上面的路径展开到FEATURE_BROWSER_EMULATION，添加对应的值。
2.在VS调试的时候，要注意添加“.vshost.exe”对应的值，否则进行调试，只能在bin或者obj的release和debug中打开才行。
