Microsoft yesterday released a new Windows 10 PC build 16237 for Insiders in the Fast ring with new features. The comapny later announced that with the Insider Preview Build 16237 for PCs it has disabled VBScript in Internet Explorer 11 by default.
Microsoft has been gradually working on phasing out VBScript out of its browsers as its not part of Edge and is officially depreciated scripting language in IE11. Blocking of VBScript was first viewed in the Creators Update and the April Cumulative Security update pushed out for Internet Explorer.
This option is currently enabled by default in the Preview Build and is currently visible for users on Fast Ring and should be available for all users once the Fall Creators Update goes public in September.
However Microsoft says that there are still methods for enabling VBScript, as IE11 is included in Windows 10 for backward compatibility.
