New Delhi: As the world awaits the Wednesday launch of Windows 10 operating system by Microsoft, with which its Indian-born chief executive Satya Nadella wants to power a billion devices in a few years, its potential efficacy in India has evoked mixed response among analysts.

While some feel it may not be a super hit, despite a free update for those with versions above Wondows 7, others say it will prove more of use on devices other than personal computers, like smart phones, tablets and other hand-helds. This apart, its acceptability at the enterprise level is also in doubt. Nevertheless, Windows 10 will also help those with pirated versions of Microsoft operating systems to migrate to an authentic version, making room for a wide range of applications to choose from.
