Hello

The mshtml.dll file is a part of the Internet Explorer web browser and is used to render HTML pages. It’s normal to have multiple versions of mshtml.dll installed on your system, especially if you have multiple versions of Internet Explorer installed.

In your case, you have two versions of mshtml.dll installed: one in the 10 branch and the other one in the 11 branch. This likely corresponds to Internet Explorer 10 and Internet Explorer 11 respectively.

As for which version is used, it depends on the version of Internet Explorer that is being used to render a particular webpage. If a webpage is being rendered using Internet Explorer 10, then the mshtml.dll file from the 10 branch will be used. Similarly, if a webpage is being rendered using Internet Explorer 11, then the mshtml.dll file from the 11 branch will be used.
