"Even as Microsoft readies a host of new ad-supported online services to battle rivals, the software maker has been mulling a plan to offer free, ad-supported versions of some of its desktop products, CNET News.com has learned.

Although no specific plans have been made, executives within Microsoft are examining whether it makes sense to release ad-supported versions of products such as Works, Money, or even the Windows operating system itself, according to internal documents seen by CNET News.com."
