A researcher has slammed talk of Internet Explorer's demise in the web browser market as "far fetched".
According to Devil Mountain Software, slightly more than 80 percent of the 22,0000 PCs in the company's community-based Exo.performance.network (Xpnet) run Internet Explorer (IE), typically for much of the day.
Devil Mountain's network collects "real-time system metrics and application usage data from Windows-based PCs and servers around the globe", according to the company's website.
That information is then used to offer up what the company calls "an authoritative" look at market share trends affecting the Windows OS.
IE isn't alone on the computers Devil Mountain monitors.
A large chunk of business users run multiple browsers, said Craig Barth, the CTO at Devil Mountain.
"There's a lot of overlap," Barth said.
Devil Mountain's performance measurement software, which has been installed on the 22,000 PCs - most of which are enterprise systems - tracks application use by monitoring processes in Windows' Tasklist.
That approach, argued Barth, shows that IE is in no danger of vanishing from the landscape, at least the corporate landscape.
"The idea that IE will go away is far fetched," Barth said.
"People who say those kinds of things simply don't have a grasp on the internal organization of enterprises, or the bureaucracy of companies. Until enterprises flush out the internal applications that rely on IE, that use unsupported and undocumented layout commands, IE isn't going anywhere. And those dinosaur applications are almost impossible to get rid of."
Other means of browser measurement have tracked a steady decline in IE use from its usage share high of 95 percent in mid-2004.
The most recent data from web metrics firm Net Applications, for instance, pegged IE's share of browser usage falling about 4.5 points in the last 18 weeks of 2009 to reach a new low of 63 percent.
Devil Mountain's XPnet data, on the other hand, shows IE use fluctuating during the same period, with the browser's process appearing on between 80 and 88 percent of PCs' Tasklists.
Barth acknowledged that XPnet's methodology counts instances of the IE process that may not be directly related to browsing, which may inflate its numbers somewhat.
"The IE engine is often embedded in other applications, and sometimes is used for custom application front ends, like online help systems," Barth said.
"The fact is that [IE's] tentacles permeate so many layers of Windows. So when Microsoft says it's painful to remove it, they're not kidding."
Microsoft has used that argument several times over the years when it's faced antitrust scrutiny.
During the 1998 antitrust trial in the case brought by the US Department of Justice and several states, Microsoft claimed that removing IE from Windows would cripple the operating system and make it unstable.
Last year, however, Microsoft surrendered to pressure from European Union regulators, and agreed to give Windows users a way to remove the browsing components of IE if they wanted to run a rival - but only after threatening to release Windows 7 minus a browser of any kind.
The fact that IE pervades the enterprise - in large part because of the need to support legacy Web applications or sites - isn't all good news for Microsoft, Barth said.
"They can move people forward, from IE6 to IE7 and IE8, but they can't scrap, say, the rendering engine and start all over," he said.
"Microsoft may want something like Chrome - mean, lean and fast - but they may never get it."
That's one reason why many corporate users run multiple browsers.
"There's really a dual personality there," said Barth.
"They may have IE running for hours because they've logged into a company application or site, but they're often running Firefox, or increasingly, Chrome at the same time."
In calling the three-way race between Microsoft's IE, Mozilla's Firefox and Google's Chrome, Barth also put down a contrarian bet. While most have tagged IE as the browser in a downward spiral, Barth thinks Firefox is the one in danger.
"The most vulnerable player is not Microsoft," Barth said, again citing IE's lock on the enterprise.
"It's Firefox, as Chrome comes up from below. Chrome is cleaner looking, faster and has better security.
Microsoft, because of its sheer weight and the legacy requirement, isn't going anywhere."
That leaves Firefox the odd browser out.
"If anyone is going to get their lunch eaten, it's Firefox," Barth said.
"It isn't the part of the big picture for anybody."
