On Tuesday, Google officially announced that it would go up against Microsoft’s policy to bundle its web-based and multimedia-focused products in its Windows operating system. Therefore, Google joins Mozilla in supporting the EU regulators who aim to restrict the software that the Redmond giant will be allowed to bundle with Windows.

Things started to go bad for Microsoft six weeks ago, when the European Commission filed a case against Microsoft, as all the European versions of Windows come with Internet Explorer. The case is similar with a previous charge against Microsoft, regarding Windows Media Player.

Google took this matter very serious, as the product manager of Google Chrome, Sundar Pinchai, stated in a blog post that the company would act as a “third party” in the antitrust case filed against Microsoft. Google’s formal position in this matter certainly means additional strain for Microsoft to cope with the commission.

Pinchai added that, currently, the web browser market suffers from lack of genuine competition. In addition, he pointed out that Google is ready to provide the European Commission with suggestions in order to regulate the market in a more liberal way.

Analysts expect that the EU regulators will not act in a similar way in which Microsoft was forced to remove Windows Media Player from the operating system. Instead, it is rumored that the European Commission will try to find a way in order to let users decide what web browser they will use. Some web sites reported that the commission would force Microsoft to include all the popular browsers in the Windows OS.
