you pick the one that has best compatibility with the html pages you have to display. Most sites no longer support IE 11, so you may have compatibility problems anyway.

Hello devs,
I'm using a WebBrowser control to show some contents and I've been told that it's using IE7 mode by default, and to emulate newer versions of IE, should change the default emulated IE mode via:
"HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorer\Main\FeatureControl\FEATURE_BROWSER_EMULATION"
WindowsApp.exe
As seen here:
Since am not familiar with html/browser protocols, shall I always enable this mode for my app on all target systems?
If so, which one?
11001 (0x2AF9 Internet Explorer 11. Webpages are displayed in IE11 edge mode, regardless of the declared !DOCTYPE directive. Failing to declare a !DOCTYPE directive causes the page to load in Quirks.
or
11000 (0x2AF8) IE11. Webpages containing standards-based !DOCTYPE directives are displayed in IE11 edge mode. Default value for IE11.
Thanks for advise :)

2023-02-18T14:22:27.5466667+00:00 Thanks, mostly html pages saved from email files, so not so advanced.
So really don't know the difference between 11001 (0x2AF9) and 11000 (0x2AF8)

How does Internet Explorer determine the document mode
The <!DOCTYPE> declaration determines whether the webpage renders some specific Quirks mode emulation (QME) behavior that is specified in the MS-HTML5 and MS-CSS21 documentation.
Based on your description, 11000 (0x2AF8) is better.
Since IE11 is no longer supported, there may be compatibility issues.
Best Regards.
