BRUSSELS — Some 100 million Europeans using Microsoft software will be asked to choose among rival Web browsers by mid-May under a deal the company struck to settle antitrust action, the European Union said Tuesday.

Microsoft Corp. is starting this month to send updates to Windows computers in Europe so that, when computer users log on, they will see a pop-up screen asking them to pick one or more of 12 free Web browsers to download and install, including Microsoft’s Internet Explorer.


The EU’s executive commission said giving consumers the chance to try an alternative to Explorer, which comes with the widely used Windows operating system, would "bring more competition and innovation in this important area."



EU antitrust regulators in December dropped their last pending antitrust case against Microsoft after the company offered to let users choose between its browser and others. This ended more than a decade of legal trouble that racked up euro1.7 billion in fines for Microsoft.

Rivals had complained that attaching Internet Explorer to Windows was an unfair way for Microsoft to put its Web software on most of the world’s computers.

The top five browsers – Microsoft’s Internet Explorer, Mozilla’s Firefox, Google Inc.’s Chrome, Apple Inc.’s Safari and Opera – will be given prominent placement on the pop-up choice screen.

The selections will rotate from computer to computer, so none of the five browsers will always be first.

Far smaller competitors, such as Avant Browser, Flock, Green Browser, K-Meleon, Maxthon, Sleipnir and Slim Browser, also will be displayed, if the user scrolls sideways.

The EU said greater browser choice also would boost the use of open Web standards, a set of guidelines on how Web sites are designed.

Rivals claim that Microsoft has not always followed these standards closely, forcing Web designers to make sites compatible with Internet Explorer, the leading browser, instead of working smoothly with other Web software.

Google spokesman Al Verney said the browser "is probably the most important piece of software on your computer today."

"Research shows many users don’t know what a browser is. We believe anything that raises awareness around browsers and increases choice is great for users and the Web," he said.

Microsoft’s browser choice screen will be used for five years in the 27-nation European Union, plus Norway, Iceland and Liechtenstein.

Microsoft could be fined 10 percent of its annual revenue if it doesn’t stick to its commitment to distribute the browser screen as agreed and to avoid any retaliation against computer manufacturers who install other browsers as a default on the computers they sell.

Users in the U.S. and elsewhere won’t see any change.
