The strategy shift emerged as a result of an interview that Bob Muglia, Microsoft's head of servers and tools division, gave at the company's Professional Developers Conference.
The furore kicked off by Mr Muglia's comments also led Microsoft boss Steve Ballmer to underscore the software giant's commitment to Silverlight technology in a statement of his own.
Mr Muglia clarified his comments in a blog post saying that exploding use of e-readers, tablets and different sorts of smartphones now made it "practically impossible" to get something like Silverlight running on all those devices.
