As part of the October 2020 Patch Tuesday security updates, Microsoft has added a new option to Windows to let system administrators disable the JScript component inside Internet Explorer.
The JScript scripting engine is an old component that was initially included with Internet Explorer 3.0 in 1996 and was Microsoft’s own dialect of the ECMAScript standard (the JavaScript language).
Development on the JScript engine ended, and the component was deprecated with the release of Internet Explorer 8.0 in 2009, but the engine remained in all Windows OS versions as a legacy component inside IE.
