Microsoft is changing its entire strategy. The company announced its new version of Office 2010 will be accessible for free. What does it mean? All your office’s software like Word, Excel, PowerPoint which you use every day, will be available from any browsers. The version will be lightweight.

It is a real upheaval that wants to make its delay in relation to Google. Let me remind you that Google launched in 2006 its own Google Documents, a free service.

Microsoft lost web and search engines’ war against Google. Moreover its operating system Windows Vista disappointed a lot. But Microsoft stays the leader in this field. In 2009, it earns $9.3 billion.

The installation of main software seems to be inevitable and it cost you at least $200. Now, a lot of users decide to make economy and use only Google Documents.

Another competitor appeared: Open Office.  Even French administration is using this free and safe system.

To prove its effectiveness, Microsoft began the competition with Google to launch Bing against Google search engine, its own search engine, which is meeting a large success. It wants to continue with Office 2010.

Some analysts think it as a risky gamble. In fact, Microsoft will offer for free its products that it is still succeeding in buying. The goal is to head users for using Bing.

The question is: who will be the winner?
