Win10 Microsoft Edge Browser: IE's old technology terminator

  
Today Microsoft listed in its official blog the traditional IE technology that is not supported by Win10's Edge browser. Microsoft said that not supporting these old technologies would have many benefits, including better interoperability, greater performance, greater security and reliability with other browsers, and reduced code complexity.

list includes ActiveX has been popular for many years and BHO, Microsoft said it will be replaced by a new, unified model modern extension.
The deleted technologies mentioned in the blog include:
ActiveX: Joined in 1996 to implement plugins and extensions. Edge natively supports PDF and Flash, and will have a new extension platform that no longer requires ActiveX;
BHO: Joined in 1997 to implement the toolbar. Edge has a new extension platform;
Document mode: IE8 joins to simulate the old engine. Edge is supported by new technologies or standards that are unstable with the about:flags switch;
VML: IE5 joins, now replaced with SVG;
VBScript: Joined in 1996. Currently JavaScript has become mainstream.
In addition to this, old techniques such as attachEvent /removeEvent, currentStyle, conditional comments, IE8 layout mode, DirectX filters and transitions have also been removed. In addition, there are other extension technologies that will be replaced by new technologies, including the Shell Helper API, custom download manager, custom security manager, MIME filtering, custom printing, accelerators, Webslices, toolbars, and more.
At the same time, Microsoft has also removed a large number of incompatible APIs and moved to a more standardized and versatile way.
If you still need to use the above old technology, you can continue to use the IE browser retained in Windows 10.
