Microsoft says that customers can now disable JScript execution in Internet Explorer 11 after installing the Windows October 2020 monthly security updates.
"Blocking Jscript helps protect against malicious actors targeting the JScript scripting engine while maintaining user productivity as core services continue to function as usual," Microsoft explains.
First of all, to be able to disable JScript execution in Internet Explorer you will first have to install the IE Cumulative security update released in April 2017.
Internet Explorer will no longer run JScript from sites using IE legacy document modes, as well as on those that are in the Internet Zone or Restricted Sites Zone.
"Microsoft will continue to provide security updates for JScript via the latest cumulative updates for Windows 10, and Cumulative Updates for Internet Explorer 11 or Monthly Rollups for Windows 8.1, Windows Server 2012, and Windows Embedded 8 Standard," Microsoft says.
