Solution 1:

The Microsoft Embedded Web Browser control runs in a Document mode of 7. So if you were to use Fiddler to see the User-agent-string you would see the IE 7 User agent string. It uses the rendering and web standards of IE7 as well.

To override this and have it use IE11 standards you will have to create a registry entry specific to your executable.

 HKEY_LOCAL_MACHINE (or HKEY_CURRENT_USER)\SOFTWARE\Microsoft\Internet Explorer\Main\FeatureControl\FEATURE_BROWSER_EMULATION

                 contoso.exe = (DWORD) 00009000
