As four out of five phones running Windows are no longer getting support or updates it's clear that there's no coming back. Even though Microsoft still will look after Windows 10 users even in mobile it is clear that the Mobile First, Cloud First strategy that CEO Satya Nadella revealed in 2014 didn't come to fruition.
Microsoft has recently been investing and focusing more and more on applications on competing platforms, namely Android and iOS that account for approximately 99.5% of new smartphones.
