Microsoft supports any PC running Windows Service Pack 3 through Windows 7 and the hardware compatible with those versions of its operating system software under its service agreements for Windows In Tune. A free 30 day trial of the software is downloadable from Microsoft's website for the product (http://bit.ly/g5dWKn). The service is being introduced at a straightforward rate for business use, at a per user, per month rate of US$11 for business and US$2.55 for academic users. As a product billed directly by Microsoft, it's still unclear how the company plans to enable its partners to bundle it into their services for customers. "We are encouraging a move from capital expenditure to operating expenditure, which Microsoft anticipates will be good for companies," Esquivel said. "The product closes the gap between small and medium enterprises and large corporations and both sectors can take advantage of the same level of support in their businesses."
