As a result of its "cross-company data intelligence", Microsoft's SmartScreen can now block zero-day drive-by attacks in Windows 10 Edge and Internet Explorer 11.

Comment:   Is the implication that IE 11's SmartScreen, under Win 7/8.1, is NOT being enhanced?

Remark:  I just read an assertion that "This [feature] will come to Windows 7 and Windows 8.1 users soon!"
