Google might have to face charges from European data protection commissioners within days after unilaterally changing privacy policies in March this year.

The Guardian reports that a group of 30 data protection commissioners from across the European Union are believed to have determined that Google has breached EU privacy laws.

Earlier this year, the search engine allegedly combined and merged existing privacy policies from various Google services including its search engine, YouTube and Google+.

Google’s privacy policy enables the company to use data from its products to improve user experience.

The search engine could make recommendations on YouTube videos based on things users have searched on it and can target advertiser to personalise search outcomes.

After the introduction of Google+, the search engine tried to merge its various products into one core Google product.

Microsoft may be fined heavily for its failure to include a crucial update in the latest version of Windows which provided European consumers a choice of browser.

EU Competition Commissioner Joaquin Almunia said: "In the information and communication industries, our work with Google is proceeding; whereas we are currently reviewing the case regarding Microsoft’s failure to keep commitments it took back in 2009 and I want to take a decision soon on the next steps."

In early next year, a decision is anticipated to be taken on Microsoft’s breach of antitrust commitments.
