Microsoft Edge並不支援包括ActiveX同埋瀏覽器輔助對象在內一些技術，而是會使用一個插件系統(Extensions)。因為ActiveX等兼容性等問題，在Windows 10之中仍然可以使用Internet Explorer 11，它和Windows 8.1中的IE完全相同，並沒有使用EdgeHTML引擎。
Microsoft Edge does not support technologies including ActiveX and browser helpers, but instead uses a system of plugins. Due to compatibility issues such as ActiveX, Internet Explorer 11 can still be used in Windows 10, which is exactly the same as IE in Windows 8.1, and does not use the EdgeHTML engine.
