Countering pressure from European regulators, Microsoft Corp plans to ship the newest version of its Windows operating system in Europe without its Internet Explorer web browser.

The abrupt reversal comes shortly before the European Commission is due to rule on antitrust charges brought against Microsoft in January, claiming that the world’s largest software company abuses its dominant position by bundling its Internet Explorer browser, shielding it from head-to-head competition with rival products.

Until now, Microsoft has claimed that the browser was an integral part of the operating system and should not be pulled out, but it now plans to do that for a European version of Windows 7, due to be rolled out later this year.

“Given the pending legal proceeding, we’ve decided that instead of including Internet Explorer in Windows 7 in Europe, we will offer it separately and on an easy-to-install basis to both computer manufacturers and users,” said Microsoft Deputy General Counsel Dave Heiner in a blog post on the company’s website on Thursday.
