It seems that Microsoft is going to experiment with free office software.  The first software will be Works 9.  Works is a lightweight package of the big brother Office and is mostly used by home users.  One the items that is not provided in Works is the presentation package (e.g. powerpoint).  Works also cost around 40 dollar, a lot lesser than Office,where people sometimes has to pay 10 times more.

The people who wants to install the free version of Works will see some little advertisments on the screen.

Microsoft hopes to be in competition with tools as Google online Docs & Spreadsheets or the free OpenOffice.

For this architecture Microsoft has requested a few weeks ago a patent for showing advertisments within Windows and other software.  This software will show advertisments to the uer based on information of the users hardware, content of documents.
