Microsoft has already started work on Windows Phone 10, and according to people close to the matter, a preview build of this new mobile operating system is expected to be unveiled next month, during a Windows 10 event in Redmond.

But pretty much everything about Windows Phone 10 is still unknown right now, despite the fact that it will most likely represent a major step forward for Microsoft in the smartphone business.

A new report coming via REM reveals a few more details about the next mobile OS prepared by Microsoft, but keep in mind that no reliable sources have been cited, so it's hard to tell whether the following info is true or not.

Key priority: make WP easier to use

Microsoft is believed to be migrating towards the same approach as for Windows 10, and the top priority for Windows Phone 10 is to become easier to use. The strategy is very similar to what happened on the desktop, as Windows 8 was considered a very confusing operating system, but things were significantly improved in Windows 8.1.

And still, Windows Phone isn't such a controversial operating system as its desktop sibling, but Microsoft anyway wants to make it easier to use, so consider this side of the platform to be significantly improved in the next release.

PC – Windows Phone transfers and vice versa

Part of Microsoft's plans to make Windows Phone 10 easier to use is also to add support for wireless synchronization with Windows computers, thus lending a hand to those who want to gain full control over their files from their computers without the need for a USB cable.

Interestingly, Microsoft is believed to be actually working on more advanced features that would also enable users to make and receive calls straight from their computers, while the PC version of Cortana will also be capable of setting up appointments or reminders straight on the phone.

Streaming files from the PC to Windows Phone and the other way around will also be possible in Windows Phone 10, the aforementioned source notes, and everything will rely on new built-in features and applications available on all Windows devices, including PCs, tablets, and smartphones.

In the end, it's worth noting that Windows Phone 10 continues to be a big enigma for every one of us, so many of the features that you've heard of in the last few months might not actually see daylight. So until Microsoft indeed confirms this project, don't take anything for granted.
