Microsoft has quietly stopped serving security updates to Internet Explorer 11 (IE11) on consumer and small business Windows 7 PCs unless the customer has successfully applied an April update for the browser.
The requirement and associated patch stoppage were similar to those Microsoft mandated for Windows 8.1 when it told customers they had to
migrate to Windows 8.1 Update by June 10 or lose their patch privileges. The Windows 7 requirement, however, affected only IE11, Microsoft's newest browser, not the operating system.
