MSHTML (also known as Trident) is the proprietary browser engine of Microsoft's Internet Explorer web browser. It debuted with the release of Internet Explorer 4 in 1997. Internet Explorer 11 for Windows 10 is no longer be supported as of June 15, 2022.[1] Microsoft recommends that users switch to the latest version of Microsoft Edge, which includes an "Internet Explorer mode".[2][3]

History[]

Discontinuation and legacy support[]

As of 2021, MSHTML is vulnerable to cyberattacks that exploit remote code execution.[4][5] Microsoft has recommended that Windows 10 and 11 users switch to the newer Microsoft Edge browser based on the Chromium engine for improved privacy and security.[2] For legacy sites that can only function with the Internet Explorer browser, Edge users can enable "Internet Explorer mode" (IE mode) to switch from Chromium to the MSHTML engine to handle such circumstances.[3] Microsoft stated that this feature would be supported in Edge until at least 2029.[1]
