By Net Applications' numbers, the affected editions were used by 55% of those running IE in April. On the plus side, that was a drop from 60% in February 2015.
IE8, for example, accounted for 29% of all instances of Internet Explorer last month, while IE7 and IE10 combined for about 10%. And most of IE9's 14.5% share had to be counted as well, since Windows Vista -- the only OS that will continue to support the edition with patches -- powered just 2% of all Windows machines in April, leaving most of IE9 running on Windows 7. Users of the latter will have to dispense with the 2011 browser in January.
At the beginning of September 2014, about 70% of all instances of IE were on the new chopping block; that has declined to 55% -- an average drop of about 1.9% per month. If users maintain that same pace over the next eight-plus months -- it's likely that migrations will pick up momentum as the drop-dead date nears -- it would mean about 39% of all IE users would find themselves cut off from security updates when the deadline hits.
Microsoft's free Windows 10 upgrade offer, which will swing into action this summer, may accelerate the demise of the affected editions: It will set the new Edge browser as the default. But Windows 10 and Edge are unlikely to prove a panacea. Enterprises, which analysts believe will wait years before jumping off Windows 7, remain wedded to Internet Explorer, particularly IE8, which last month was run by almost three out of every 10 copies of IE used. Businesses are unlike to migrate any significant number of their PCs to Windows 10 before next January.
