Users of Internet Explorer (IE) were in no hurry last month to discard older versions, even after Microsoft told them that their browsers will drop off the support list in early 2016.
In a surprise announcement on Aug. 7, Microsoft said that after Jan. 12, 2016, it would support IE9 only on Windows Vista, IE10 only on Windows Server 2012, and only IE11 on Windows 7 and Windows 8.1.
IE7 and IE8 will drop off support completely, but others on certain editions of Windows — like IE10 on Windows 7 — will also get the patch axe.
The browsers will continue working, but Microsoft will halt technical support and stop serving security updates for the banned versions. Because of the large number of critical vulnerabilities Microsoft patches in its browser — 110 in the last three months — it will be extremely risky running an unsupported version.
But Microsoft's mandate did little to change the user share of the various versions of IE last month as measured by metrics vendor Net Applications.
IE9 actually gained ground. The browser, which is the newest able to run on Vista, added two-tenths of a percentage point to its user share to average 9.2% for August. But because Vista currently powers just 3% of all Windows computers, a majority of IE9 runs on Windows 7, which must dispense with the 2011 browser in under a year and a half.
IE8 will be an even bigger problem. The browser, which is the default for many of the Windows XP PCs still in operation, also was adopted by large numbers of businesses as the standard for Windows 7. That showed in Net Applications' statistics: IE8 accounted for 21.4% of all browsers last month, down just two-tenths of a percentage point, and 36.6% of all copies of Internet Explorer.
(The difference between the numbers for all browsers and only IE was because Internet Explorer has a 58.5% share of the browser space, not 100%.)
IE6 and IE7 also declined last month, but by minuscule amounts of two-tenths of a point and less than half of one-tenth of a point, respectively. IE6, although no longer supported on Windows XP, is still patched on Windows Server 2003, which is slated for retirement in July 2015.
IE10 barely moved, too: Its user share dropped by less than one-tenth of a point to 6.2% of all browsers, and to 10.6% of all copies of IE.
The only bright spot was 2013's IE11, which gained about eight-tenths of a percentage point to average 17.6% of all browsers, 30% of all copies of IE.
By the numbers, Microsoft's customers will have a very hard time scrubbing out-of-date versions of IE by 2016. If IE8 was to magically disappear — which it will not — it would have to shed 1.3 percentage points each month. That would represent an increase of more than 2,000% from its six-month average decline.
