In the midst of the launch of the new Windows Live services, which included the update to Games for Windows Live yesterday, the Microsoft Store officially opened for US businesses.
Previously, the company opened at UK, Germany, and Korea, and both hardware and software would be sold by Microsoft. Furthermore, it also offers the option to purchase software, either as physical media or as a download.
The store would instantly provide many versions of Vista (both full versions and upgrades) and Office and its related components.
