Microsoft HTA/Changing Internet Explorer Version
By default, HTAs display webpages in Compatibility View, this means that content is displayed in Internet Explorer 7. It's just Internet Explorer 6 but with few more features. To change IE version, you need to use
<meta http-equiv="x-ua-compatible" content="ie=yourversion"> in
<head> of page. The lastest IE version is 11, but note that IE 10 has dropped support for
<hta:application> settings, so if you want settings, use ie9, that support some HTML5 (for example SVG) and CSS3 (for example box-shadow) features. If you don't need settings, set ie=edge, that will render page in Microsoft Edge.
This example is SVG enabled:
