How to make MS Webbrowser control behave the same as IE11

Hi, 

I wrote a simple app using the Webbrowser control, basically consisting out of an address bar, a button and a browser window. Added a registry key for  the application [HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\Main\FeatureControl\FEATURE_BROWSER_EMULATION : BasicBrowser.exe REG_DWORD 0x00002af8 (11000) ]

Using IE11 and accessing the site https://music.microsoft.com/Authentication/GoToWLSignIn, I provide a user id and password and this brings me to https://music.microsoft.com.

However, when using my simple browser app, after submitting the login credentials, the app only displays the spinner and finally displays a screen saying "Sorry, we can't sign-in to Groove right now. We're working on it. Please try again soon" 

Are there any other registry entries that need to be added to make the Webbrowser control act like the real IE11?

Any help would be greatly appreciated.

Regards,

Luc
