Microsoft is eager to expand its Xbox Live service beyond the console space, a demonstration for the Xbox Live functionality on Windows 8 was given on Thursday and it looks like that strategy is going to expand even further next year.

Microsoft confirmed that Xbox Live is coming to PCs next year, when the new Windows 8 operating system launches.the cross platform possibilities of the new operating system were on full display.  With Xbox Live coming to the new interface, and plenty of back-end optimizations, a whole slew of new features that work with Xbox Live will be coming to Windows 8.
