The Microsoft Windows 10 Mobile operating system running on Lumia phones was conceivably a feasible competitor to Google's Android-based phones and Apple's iOS a couple of years ago. That stage was short-lived and now, based on the latest earnings call from Microsoft, it seems safe to say that the software giant will no longer be investing more time and money in Windows Phone.

In this quarter, Windows Phone saw a considerable decline -- from $735 million to $730 million -- meaning, the phone revenue was just $5 million. No prizes for guessing, this is imperceptible as far as the overall revenue model of Microsoft is concerned. In fact, Forbes contributor Curtis Silver claims this could be less than what the company shells out for K-cups for the Keurig machines in the break room.

While multiple sources have been reporting about Microsoft's decision to oust Windows Phone, the company continued to refrain from making an official statement, clarifying the same. Microsoft's lips are still sealed; however, Microsoft's quarter earnings report (which was published by the company) gives the speculation about Windows phones demise its seal of approval.

It is no longer listed as a platform slated to receive investments. Originally spotted by Portuguese website Doctor Windows Phone (via DeccanChronicle), the mobile platform in question will not receive any further enhancements.

Another report from Softpedia indicated that Microsoft is prepping to complete Windows Phone wind-down by June as the Redmond-based tech titan tries to step away from phones in this quarter. This piece of information was shared via a tweet by technology journalist and blogger, Paul Thurrott.

Meanwhile, multiple sources suggest the company is hard at works on a new project -- Windows 10 on ARM. Microsoft will be leaving no stone unturned in their bid to remain a key player in the mobile business and the aforesaid project is expected to grease the wheels for the company. If this comes to fruition, tech enthusiasts will be able to power up a slew of devices including their laptops, PCs and a new a type of smartphones with the system.
