Even as the release of Internet Explorer 10 (IE10) looms for Windows 7, enterprises are standardizing on the four-year-old IE8 instead, a developer of browser management software said today. "Customers aren't going beyond IE8, and they say they'll stay with it for the next five years," said Gary Share, president and chief operating officer of Browsium, a Washington state-based company that recently released Catalyst, a tool that lets IT staffs manage multiple browsers. "We do not have a single customer using Windows 7 and IE9."
