Microsoft is considering releasing both Windows Phone and Windows RT for free in future versions as a way of pushing back against the dominance of Google’s Android platform in the mobile segment. This is part of a move to push the two platforms on a license-free model which could happen when the software giant pushes its next revision of the Windows platform, Windows Threshold. The move would mark a considerable change for Microsoft, which has for decades relied on the licensing of its Windows operating system for a large portion of its revenue.
