While we do know for a fact that Internet Explorer will largely remain unchanged in Windows 10, technologies like ActiveX and others will not be supported in Microsoft Edge.
Neat, as the ultimate goal is to offer a safe and secure browsing experience with the new web browser, as the company very recently highlighted in elaborate detail — Edge is being designed as a reliable and secure solution for all devices it runs on, from PCs to tablets and phones.
For this reason, the software titan has decided not to include old technologies that were often used by cybercriminals to hack into computers by directing Internet Explorer to access malicious websites.
Microsoft talked about this in a separate blog post, explaining:
“The need for ActiveX controls has been significantly reduced by HTML5-era capabilities, which also produces interoperable code across browsers.”
ActiveX, for those of you old enough to remember this, was introduced with much fanfare in 1996, allowing developers the ability to integrate additional technologies on their websites when viewed with Internet Explorer.
The browser downloaded and installed all those controls — this made it very easy for attackers to compromise a vulnerable system.
Future versions of Edge will forgo the need of these dedicated controls, and offer built-in support to replace the need for ActiveX.
Same goes for Browser Helper Objects (BHO), a technology that Microsoft introduced in 1997, which is used by the majority of toolbars for Internet Explorer. This too, will not be included in Edge, when the new web browser makes its debut with Windows 10 this summer.
