On January 12, 2016, the support clock ran out for Internet Explorer (IE) 8, 9 and 10. True, there are a few exceptions, IE 9 on Vista and Windows Server 2008, and IE 10 on Windows Server 2012 still live. But for most Windows users the time has come to to switch to a new browser.
Of course, you could stick with a browser that’s no longer supported, but sooner or later that way leads to a security disaster. Don’t do this!
